Correlation of Radiological Findings (High Resolution Computed Tomography Chest) with Anti-SARS-COV-2 Antibodies in Patients Visiting Tertiary Care Hospitals

Background: Coronavirus (COVID 19) pandemic has taken so many lives and has contributed to an increase in morbidity due to its complications. The research is still in infancy and much has yet to be investigated. Objective: To correlate the HRCT findings on chest with antibody testing in patients visiting tertiary care hospitals in Lahore. Methodology: Three hundred and thirty-two patients with mild, moderate and severe symptoms of COVID 19 were recruited. Those with raised CRP levels were sent for HRCT chest and PCR testing as protocol of the hospitals. All patients were tested with Rapid antibody kits for reactivity. Results: Showed that males were affected more than females. Similarly, non-health care workers were more affected. All patients with bilateral involvement of lungs on HRCT chest and positive PCR findings also tested reactive on antibody testing. However, a few people with bilateral lung involvement and negative on PCR testing got reactive results on Rapid antibody testing. Linear regression model shows significant correlation of HRCT chest findings with Ant-SARC- COV 2 antibodies. Conclusion: HRCT findings (Unilateral and bilateral lung infiltrates) correlated significantly with Anti SARC-COV 2 Antibodies.

Urinary collecting system invasion on multiphasic CT in renal cell carcinomas: prevalence, characteristics, and clinical significance.

The aim of this study was to determine the prevalence of collecting system invasion (CSI) on multiphasic CT, validate the pathological findings, and investigate the relationship between CSI and clinical outcomes in patients with renal cell carcinomas (RCC). Patients pathologically diagnosed with RCC between January 2008 and December 2017 were retrospectively enrolled in this study. They were divided into two groups according to the presence of CSI on multiphasic CT images. Patients' clinical characteristics, radiological findings, and overall survival (OS) and recurrence-free survival (RFS) rates were analyzed and compared between the groups. In addition, the correlation of radiological findings with pathological findings was investigated. Among the included 347 kidneys of 340 patients, CSI was observed in 11 kidneys (3%; 95% confidence interval, 1.3-5.0%). In all the 11 kidneys, the tumors were pathologically diagnosed as clear cell RCC, and in one kidney, the tumor also had sarcomatoid features. When pathological CSI served as the standard of reference, the sensitivity, specificity, and accuracy of CSI on CT were 50%, 99.7%, and 97.1%, respectively. The OS and RFS rates were not significantly different between patients with CSI on CT and those without CSI. This study found that the prevalence of RCC-related CSI was 3%. Because of the low prevalence, we cannot exclude the possibility that CSI on CT would be associated with the OS and RFS. Further studies are needed to determine whether CSI on CT can be an independent prognostic factor for survival in patients with RCC.

Radiological diagnosis of breast cancer patients according to their corresponding histopathological features

SUMMARY Accurate correlation of radiological findings with corresponding histopathologic features is considered one of the pivotal aspects of image analysis of breast disorders. We previously examined the correlation between radiological findings including mammography, ultrasonography and multidetector row helical computed tomography, and the corresponding histopathology of patients with breast cancer. Classifying the radiological diagnoses according to their phenotypes – evaluated by histopathological and immunohistochemical analysis – did reveal distinct differences among different cancer subtypes. These proposed radiological diagnostic criteria, based on biological characteristics, may provide a more accurate prediction of the clinical and/or biological behavior of breast cancer.

Accuracy of magnetic resonance imaging in predicting residual disease in patients treated for stage IB2/II cervical carcinoma with chemoradiation therapy: Correlation of radiological findings with histology of the cervix

Correlation of Radiologic Findings and Clinical Outcome in Pharyngeal Pouch Stapling

We undertook to identify any correlation between radiologic findings and clinical outcome in pharyngeal pouch surgery. We performed a retrospective case control study in a teaching hospital in Dundee, Scotland. The subjects were 21 patients who underwent pharyngeal pouch stapling. We used a novel method to measure the characteristics of each pouch by focusing on a triangular area in the neck of the pouch. A correlation was found between the radiologic preoperative findings and the clinical outcome. A short triangle was more likely to result in postoperative complications, whereas a long one was more likely to require revision surgery. It is possible to predict the surgical outcome from the radiologic characteristics of the diverticulum. We believe that our findings may have important clinical implications.

Duodenitis in children: correlation of radiologic findings with endoscopic and pathologic findings.

To determine the accuracy of barium studies in the diagnosis of duodenitis in children. Seventy-five children (45 boys and 30 girls; mean age, 9 years) underwent upper gastrointestinal (GI) examinations. Twenty-four of the children had biopsy-proved duodenitis, and 51 were healthy control subjects. Radiologic findings were reviewed by two experienced, blinded observers and correlated with endoscopic and histologic results. Duodenal mucosal-fold thickness was measured on spot radiographs (20% magnification), and the extent of disease was evaluated. Of 15 children with mild duodenitis, 13 had normal radiologic findings and 11 had normal findings at esophagogastroduodenoscopy. Of nine children with severe duodenitis, all had friability or ulceration at endoscopy and mucosal-fold thickening of greater than or equal to 4 mm (> or = 3 mm in one infant aged less than 1 year) at upper GI examination. Mucosal-fold thickening was diffuse in patients with celiac, autoimmune, and adenovirus disease and was proximal in patients with peptic ulcer and Crohn disease. Of 51 control subjects, 50 had normal radiologic results, while 47 had normal endoscopic results. The sensitivity of upper GI examination for mild and severe duodenitis combined was 46% with a specificity of 98%, whereas endoscopy had a sensitivity of 54% and specificity of 92%. Mucosal-fold thickening was a specific sign of duodenitis in children and should be investigated. Upper GI examination yielded results similar to those at endoscopy.

COMPUTER PROCESSING OF NEURORADIOLOGICAL REPORTS. AN INTRODUCTION TO THE APPLICATION OF THE VARIABLE-FIELD-LENGTH FORMAT AND MEDTRAN.

Advances in the application of computer technology to medicine have been proceeding at an ever-increasing rate (2–6, 12–18, 21). This report deals with a technic that the authors have recently applied to radiology. The method combines routine dictation and typing of patients' radiological reports utilizing a special, commercially available typewriter. This typewriter will simultaneously prepare the material in the form of hard copy for routine use, and punch paper tape which is in machine language for computer input, storage, and analysis. The procedure was adapted from a previously described program of computer processing of neurological and neurosurgical case summaries (10, 11). The technic is now being routinely applied to neuroradiology reports of special procedures such as pneumoencephalography, ventriculography, angiography, and myelography performed at University Hospital and Bellevue Hospital of the New York University Medical Center. The purpose of adopting this process is to take full advantage of the high-speed digital computer so that the data in the reports may be utilized in various types of research. These include statistical studies of records, correlation of radiological findings with clinical and laboratory data, and retrieval of reports for follow-up patient care. Method The main purpose of the technic described is to produce readable hard copies of the report for the chart, files, administrative needs, etc., and simultaneously have the report produced in the form of machine language so that it can be placed in a computer for storage and appropriate analysis. This is accomplished in such a manner as to encroach as little as possible on the physician's time and effort while he dictates his routine radiology report. The method of accomplishing this has been previously described in detail elsewhere (10, 11), but a synopsis will be presented here. (a) Dictation: All reports are dictated according to a rigid format in fixed sequence which is modified to the needs of the radiologist. The formats contain two sections. The first is termed the fixed-field for statistical and identifying data, i.e., name of patient, age, hospital, ward, date of procedure, etc. (Tables I to III). The second section, termed the variable-field, contains the description of the procedure and the radiographic findings. The variable-field is in the form of first, second, and third order paragraphs (Tables II and III). The amount of verbal and numerical data that can be placed in this section is virtually unlimited. The first and second order paragraphs are coded for computer identification, while the third order paragraphs contain the data of the report.
