Correlation between alveolar bone level and mandibular trabecular Pattern In Periodontitis Patients Of Belgaum: A Radiological Survey

Introduction – Bone is a living, dynamic tissue, which undergoes remodelling throughout life, especially in adults. Deterioration of bone microarchitecture involves changes in the thickness and number of trabeculae, separation of trabeculae, and morphometric changes in the trabecula. Some studies suggest that changes in bone metabolism are reflected more so in the trabecular pattern rather than the bone mineral density. To further explore this, a short-study was carried out to investigate radiographically the relationship between the alveolar bone level and different trabecular bone patterns in periodontitis patients. Materials and Methods – A set of panoramic radiographs of 30 subjects was taken from radiology section, which included both males and females. Average alveolar bone level in a quadrant was calculated for each patient. Trabecular bone in the mandibular premolar area was categorised using Taguchi et alcriteria. The two variables were analysed using Spearman’s correlation coefficient and regression analysis models. Result – A significant positive correlation was found between alveolar bone loss and density of trabecular pattern. Conclusion–With increasing grade of trabeculation, a larger alveolar bone loss can be expected. This may prove to be useful in preventing tooth loss as well as in implant planning. KeyWords: alveolar bone, trabecular bone pattern, panoramic radiographs.

Covid-19: As a Fear Factor in Response to Stroke Code and Other Interventional Radiology Emergencies?

The COVID-19 coronavirus crisis has posed an international challenge for all health systems. The first patient registered in Spain with the COVID-19 coronavirus was known on January 31, and the state of alarm was declared on March 14, 2020. The advance of the infection worldwide has caused a modification of the usual pattern in hospital emergency responses. This study describes the incidence of emergencies in the interventional radiology section of the Marqués de Valdecilla University Hospital and analyzes whether the presence of COVID-19 caused a decrease in the number of patients treated especially for ischemic strokes. A descriptive cross-sectional study was carried out on a sample of 236 patients treated at the interventional radiology on call between June 1, 2019 and May 10, 2020, at the Marqués de Valdecilla University Hospital. No specific results were found that indicate a decrease in the incidence of urgent procedures, especially mechanical thrombectomies in patients with ischemic strokes performed by the interventional radiology team since the establishment of the alarm state by COVID-19 in Cantabria. Patients' fear of contracting COVID-19 infection in the hospital environment has not led to a decrease in urgent procedures, especially for ischemic strokes.

Interventional radiology and COVID-19: How to face the challenge?

With the sudden outbreak of Coronavirus disease-19 (COVID-19) in China, and its rapid spread across the continents over a short period of time, healthcare workers are posed with the challenge of managing these patients as well protecting themselves from getting infected. Since interventional radiology deals with both elective and emergency services, wherein close patient contact is a norm, there is a substantial risk of acquiring and transmitting infection. Given the circumstances, it is imperative to develop broadly applicable guidelines to utilize the available resources in an optimal fashion and limit transmission of disease. This brief review deals with infection control measures within the Interventional Radiology department or section and possible recommendations that can be adopted at the institutional level.

The practice of emergency radiology throughout Europe: a survey from the European Society of Emergency Radiology on volume, staffing, equipment, and scheduling

To obtain information from radiology departments throughout Europe regarding the practice of emergency radiology METHODS: A survey which comprised of 24 questions was developed and made available online. The questionnaire was sent to 1097 chairs of radiology departments throughout Europe using the ESR database. All data were collected and analyzed using IBM SPSS Statistics software, version 20 (IBM). A total of 1097 radiologists were asked to participate, 109 responded to our survey. The response rate was 10%. From our survey, 71.6% of the hospitals had more than 500 beds. Ninety-eight percent of hospitals have an active teaching affiliation. In large trauma centers, emergency radiology was considered a dedicated section. Fifty-three percent of institutions have dedicated emergency radiology sections. Less than 30% had all imaging modalities available. Seventy-nine percent of institutions have 24/7 coverage by staff radiologists. Emergency radiologists interpret cross-sectional body imaging, US scans, and basic CT/MRI neuroimaging in more than 50% of responding institutions. Cardiac imaging examinations/procedures are usually performed by cardiologist in 53% of institutions, while non-cardiac vascular procedures are largely performed and interpreted by interventional radiologists. Most people consider the European Diploma in Emergency Radiology an essential tool to advance the education and the dissemination of information within the specialty of emergency radiology. Emergency radiologists have an active role in the emergency medical team. Indeed, based upon our survey, they have to interact with emergency physicians and surgeons in the management of critically ill patients. A broad skillset from ultrasonography and basic neuroimaging is required. • At most major trauma centers in Europe, emergency imaging is currently performed by all radiologists in specific units who are designated in the emergency department. • Radiologists in the emergency section at present have a broad skillset, which includes cross-sectional body imaging, ultrasonography, and basic neuroimaging of the brain and spine. • A dedicated curriculum that certifies a subspecialty in emergency radiology with a diploma offered by the European Society of Emergency Radiology demonstrates a great interest by the vast majority of the respondents.

Imaging of the Ribs: From A to BX

The ribs are evaluated by radiologists of all subspecialties. A recent informal review of intradepartmental consults by the musculoskeletal radiology section at our institution revealed that approximately 20% of all queries involved the ribs. To educate radiologists further, an organized review of the rib in medical imaging was performed. The aims of this article are to expose radiologists to important clinical conditions in which the rib can be involved and to provide essential information to guide diagnosis and management. In the event that biopsy is indicated, we characterize three types of lesions and provide techniques for maximizing diagnostic yield.

Improved Utilization Following Conversion of a Fluoroscopy Suite to Hybrid CT/Angiography System

PurposeTo assess changes in operational utilization following conversion of a single IR suite to a hybrid CT/angiography (Angio-CT) system at an academic tertiary care center. Materials and MethodsThe total number of interventional procedures and diagnostic CT examinations performed in 29 rooms (20 diagnostic radiology, 7 IR, 2 shared between divisions) was calculated in the 24 months before conversion of an IR suite to Angio-CT and 12 months after conversion. The total number of IR procedures (global IR/month) and diagnostic CT scans per month (global CT/month) in both before and after conversion periods was calculated and defined as baseline institutional growth. This was compared against the change in the number of IR procedures performed in the before and after periods in the converted room (Angio-CT/month) as well as the number of diagnostic CT scans performed in the shared rooms (shared CT/month). ResultsThe percent change in global CT and global IR from the before to the after periods was 39.2% and 3.1%, respectively. Shared CT per month and Angio-CT per month increased by 46.7% and 12.0% across the same time periods, respectively. The ratio of the percent increase in Angio-CT per month to percent increase in global IR per month was 3.87. The ratio of the percent increase in shared CT per month to percent increase in global CT per month was 1.19. ConclusionsOperational utilization improved in both diagnostic radiology and IR sections following conversion of a conventional fluoroscopic IR suite to an Angio-CT room.

Prospective Analysis of Radiology Resource Utilization and Outcomes for Participation in Oncology Multidisciplinary Conferences

Rationale and ObjectivesRadiology participation is necessary in oncology multidisciplinary conferences (MDCs), but the resources required to do so are often unaccounted for. In this prospective study we provide an analysis of resource utilization as a function of outcomes for all MDCs covered by an entire radiology section and provide a time-based cost estimate.Materials and MethodsFollowing institutional review board approval, prospective data on all MDCs covered by abdominal radiologists at a single tertiary care academic center were obtained over nine weeks. A predefined questionnaire was used by a single observer who attended every imaging review and recorded the total time spent by the radiologists and several outcome measures. The total time recorded was used to provide a time-based cost estimate using a national salary survey.ResultsSix radiologists participated in a total of 57 MDCs, with 577 cases reviewed and discussed. 181 (31%) cases were performed at outside facilities requiring full reinterpretation. Clinically significant revisions to original reports were recorded in 107 (18.5%) cases. Radiologist input directly resulted in alteration of cancer staging in 65 (11%) patients and specific recommendations for follow-up diagnostic workup in 280 (48%) of cases. The mean total time devoted by the staff radiologist per week to MDCs was 18.7 hours/week, nearly a half of full-time effort, or 8% of total effort per radiologist. The total annual projected cost of radiology coverage for each weekly MDC was $26,920.ConclusionSection-wide radiologist participation in MDCs directly resulted in change in clinical management in nearly half of reviewed cases. This was achieved at a notable time cost, highlighting the need for efficient integration of radiology MDC participation into radiologist workflow and compensation models.

Neuroradiology training in EU: international survey of 31 countries within UEMS frame

ObjectiveTo assess the current framework of interventional and diagnostic neuroradiology in EuropeMethodsThe UEMS (European Union of Medical Specialists) Section of Radiology and the subspecialty UEMS Division of Neuroradiology collected by e-mail a survey on the situation of diagnostic and Interventional Neuroradiology’ training and practice in Europe. The questionnaire was sent to the national delegates from 31 UEMS member countries, belonging to the European Union, the European Economic Area and the Council of Europe. In case of uncertain or discordant replies, the survey envisaged the involvement of neuroradiology scientific societies’ experts for providing a decisive answer.ResultsA formal post-residency training in diagnostic and interventional neuroradiology is provided respectively by 12/31 and 20/31 of the European countries. Currently, for becoming neuroradiologist in a country without fellowship program, a radiologist should (1) get subspecialty credits, (2) follow training inside national or international neuroradiology departments, or (3) perform the main reporting activity in neuroradiology.In nearly 2/3 of the States included in the survey, the neurointerventional procedures are provided by radiologists (22/31) and in the most frequent scenario a specific training in neurovascular is required to all radiologist or non-radiologist candidates (18/31).ConclusionsThe European framework of neuroradiology’s training and practice that emerged through this survey is fragmented, but there is an increasing attention by European scientific societies and institutions to create a common path of training and practice that can guarantee high educational and patient care standards.

ESUR/ESUI consensus statements on multi-parametric MRI for the detection of clinically significant prostate cancer: quality requirements for image acquisition, interpretation and radiologists\u2019 training

ObjectivesThis study aims to define consensus-based criteria for acquiring and reporting prostate MRI and establishing prerequisites for image quality.MethodsA total of 44 leading urologists and urogenital radiologists who are experts in prostate cancer imaging from the European Society of Urogenital Radiology (ESUR) and EAU Section of Urologic Imaging (ESUI) participated in a Delphi consensus process. Panellists completed two rounds of questionnaires with 55 items under three headings: image quality assessment, interpretation and reporting, and radiologists’ experience plus training centres. Of 55 questions, 31 were rated for agreement on a 9-point scale, and 24 were multiple-choice or open. For agreement items, there was consensus agreement with an agreement ≥ 70% (score 7–9) and disagreement of ≤ 15% of the panellists. For the other questions, a consensus was considered with ≥ 50% of votes.ResultsTwenty-four out of 31 of agreement items and 11/16 of other questions reached consensus. Agreement statements were (1) reporting of image quality should be performed and implemented into clinical practice; (2) for interpretation performance, radiologists should use self-performance tests with histopathology feedback, compare their interpretation with expert-reading and use external performance assessments; and (3) radiologists must attend theoretical and hands-on courses before interpreting prostate MRI. Limitations are that the results are expert opinions and not based on systematic reviews or meta-analyses. There was no consensus on outcomes statements of prostate MRI assessment as quality marker.ConclusionsAn ESUR and ESUI expert panel showed high agreement (74%) on issues improving prostate MRI quality. Checking and reporting of image quality are mandatory. Prostate radiologists should attend theoretical and hands-on courses, followed by supervised education, and must perform regular performance assessments.Key Points• Multi-parametric MRI in the diagnostic pathway of prostate cancer has a well-established upfront role in the recently updated European Association of Urology guideline and American Urological Association recommendations.• Suboptimal image acquisition and reporting at an individual level will result in clinicians losing confidence in the technique and returning to the (non-MRI) systematic biopsy pathway. Therefore, it is crucial to establish quality criteria for the acquisition and reporting of mpMRI.• To ensure high-quality prostate MRI, experts consider checking and reporting of image quality mandatory. Prostate radiologists must attend theoretical and hands-on courses, followed by supervised education, and must perform regular self- and external performance assessments.

Pediatric Radiology Fellowship Creation as an International Education Outreach Effort in Ethiopia.

In 2008, there were no pediatric radiologists in Ethiopia, a country of 100 million people. The radiology residency programs lacked training in pediatric imaging acquisition and interpretation. We established an accredited local pediatric radiology fellowship program in Ethiopia. With assistance from US faculty from the Children's Hospital of Philadelphia, Ethiopian radiologists created a 2-year fellowship training program in a university-based Ethiopian radiology residency program that incorporated formal lectures and seminars, case tutorials, journal clubs, teleradiological conferences, paper presentations, and online courses from collaborating institutions. Formal accreditation of the program was achieved from the university, and core values were established to ensure sustainability and self-sufficiency. The Ethiopian institution provided funding for the fellows, and US faculty volunteered their time. In 2015, 2 radiologists were recruited to the new fellowship; after graduation in 2017, they formed the first pediatric radiology section at the Ethiopian institution. Three new fellows were recruited in 2019, and the program is now self-sustaining. Pediatric imaging training has also been added to the radiology residency. Establishing a pediatric radiology fellowship in a country with high need but little existing faculty expertise is feasible through outreach efforts.

Precision of 3D MSCT Scan Diagnostcs on Maxillofacial Trauma Compared to Stabilization and Instrumentation Operation Results

Handling standardized radiological readings of patients with maxillofacial trauma, particularly in radiology are currently absent. Appropriate and accurate of radiological reading results could be as the guideline for surgeons in determining surgical procedures. This study aimed to evaluate the diagnostic accuracy of maxillofacial fracture patients with head 3D CT scan compared to stabilization and instrumentation results as gold standard. Secondary data that derived from medical records were used as 29 patients with clinical maxillofacial trauma enrolled in this study at Radiology Section of Dr.Soetomo General Hospital from November 2012 to March 2013. The Mc Nemar test showed that there was no significant difference between the 3D CT scan results and the stabilization also instrumentation results with p = 1.000 (p> 0.05). While, the result was by calculating Kappa coefficient that a high suitability between head 3D CT scans and stabilization also instrumentation result with κ = 1.000, p = 0.000 (p <0.05).There were several complications in the form of Cranii Bone Fraktur (25%), intracranial complication (15.24%), Haematosinus (52.38%) and Soft tissue haematoma (32.38%) with most intracranial complications ICH (31.25%), then, most soft tissue complications were in the Orbita region (26.47%) and the most common Haematosinus complications regarding Sinus Ethmoid and Maksilaris (29.09%). It concluded that the 3D CT scan results were in accordance with the results of stabilization and instrumentation operations.

Client satisfaction on Emergency department services and quality of emergency medical care in Ethiopia: A systematic review.

The utilization of the emergency department to provide an emergency medical services is crucial for the communities who need an urgent medical care that is associated with various cases. This aim of this review was to describe the client satisfaction on the services of Emergency department and the quality of emergency medical care in Ethiopia. We searched peer-reviewed published articles related to clients' satisfaction on emergency department services and the quality of emergency medical care between January 2000 and December 2017. The articles were retrieved from databases of PubMed, Scopus, Ovid, Google Scholar, MEDLINE, EMBASE and ScienceDirect. Furthermore, studies published in other language than English was excluded. A total of 2094 participants: 906 (43%) males and 1188 (57%) females were recruited in those reviewed papers to express their satisfaction on the service and the quality of emergency medical care of the Emergency department. Based on the study findings, majority 1177 (56%) of the participants were satisfied by emergency outpatient department (OPD) services. The majority 1018 (83%) of the participants were satisfied with the manner that was showed by the staffs working at the Emergency OPD. In similar manner, the satisfaction level of the participants in the Emergency OPD towards the accessibility of the emergency care services, courtesy of the staffs, quality of the services, physical environments, and existence of good communication with services provider were 72%, 97%, 81.5%, 55%, and 66%, respectively while 97.2% of them were dissatisfied with their privacy. On the other hand, 76% of the participants were satisfied with the service provided in the radiology section and other laboratory work. This study finding shown that there was the variety of client perception on the emergency department and its quality care. Therefore, Emergency outpatient department should be raised progressively further by health care managers, governmental executives, EMS directorate, and others to address the efficient attribute of deprived value of health care and continuity of care delivery system being tied with new policy in Ethiopia.

Untethering the Queue based on Multi Channel Access (MCA) Technology at Hospital Radiology Section

Background: Information technology is developing rapidly over time, but there are many companies do not make use of it to support their operational activities. One example is the queue system in the Radiology Section of Sanglah Hospital, which operates the conventional queue system.Objective: The problem occurs in this queue system is inefficient waiting time because the patients must come early and wait in line in the hospital waiting rooms. Many patients thereafter decide going home first or doing other activities. Another problem is it triggers double costs of transportation. The purpose of this study is to improve patients comfort while waiting in queue by applying untethering the queue. Untethering the queue is a service that allows people to be in a queue even though they are not in the waiting room.Methods: The system applies the FCFS (First Come First Serve) algorithm to manage patients’ queue and integrates this queue system with Telegram and SMS gateway. It makes patients easier to take queue numbers and receive notification of health service time from the Radiology Section of Sanglah Hospital.Result: As a result of this study is an untethering the queue application which is web-based queue system integrated to Telegram and SMS gateway. The daily queue services in the Radiology Section of Hospital can be improved through this application.Conclusion: Patients can only come to the hospital when the queue numbers obtained nearly the health service time so that it leads to time efficient and comfort while waiting in queue.Keywords:First Come First Serve, Multi Channel Access, SMS, Telegram, Untethering the Queue

Dosimetric depth distribution of Fukushima-derived 137Cs in coniferous forest soil

The ambient dose rate (ADR) in a coniferous forest floor contaminated by Fukushima-derived 137Cs was calculated for small temporal scale as a function of depth. The calculated total ADR was statistically evaluated along the soil vertical strata and among the sampling time series. Moreover, the contribution of the forest floor components to the total radiation dose were examined. Accordingly, the litter and fragmented organic layers accounted for about 58 to 96% (mean 77 ± 14%) of the ambient dose, indicating the organic layer is a chief sources of external radiation exposure, and an important radiological soil section.
