Multidetector computed tomography in the evaluation of gastric malignancy; A multicenteric study

ObjectiveThe aim of this work is to highlight the diagnostic value of multidetector CT in assessment of gastric malignancy compared to surgical and pathological results. MethodA Multicenter study was conducted from (October 2011–March 2014). Thirty-five patients were included, eight females and twenty-seven males with mean age 50 years (34–81). All patients were subjected to; Full history taking and physical examination, Multidetector Computed Tomography (MDCT), and Upper Gastro intestinal endoscopy. Triphasic CT was used using oral and IV contrast where scanning at arterial phase cuts were taken after 15 s followed by portovenous 20–25 s after the arterial phase. Results74% of Lesions detected at the study were mural thickening, with adenocarcinoma pathology. MDCT T staging compared to pathological staging was highly significant. Only 33 cases had pathological reports suitable for comparison with the MDCT staging. True positive cases were 30, false positive cases were 2 cases and false negative was only one case, Thus giving sensitivity 96.7% and accuracy 91%. ConclusionMultidetector CT can play an important role in diagnosis and preoperative staging of gastric cancer.

Role of Multi-Detector CT in Assessment of Patients Suspected with Chronic Inflammatory Bowel Disease

Background:Crohn’s disease and ulcerative colitis evolve with a relapsing and remitting course. Determination of inflammatory state is crucial for the assessment of disease activity and for tailoring therapy .Computed tomography enterography (CTE) has become a main modality for the evaluation of inflammatory bowel disease (IBD). It simultaneously offers visualization of the small bowel and extra intestinal status, which is helpful for diagnosing IBD. Crohn disease has long segmental enhancing wall thickening related with the eccentric longitudinal distribution. In addition, mural stratification, fibrofatty proliferation, positive comb sign by increased mesenteric vascularity and internal/perianal fistula are characteristics of Crohn disease and can be identified on CTE. Each of CTE findings for the IBDs is helpful for differential diagnosis. The main disadvantage of this technique is the requisite radiation exposure of patients, particularly in young patients. However, recent development of advanced CT techniques is promising for radiation dose reduction without compromising diagnostic image quality

Role of multidetector computed tomography in assessment of fibro-osseous lesions of the craniofacial complex

AimTo assess the role of multidetector CT in assessment of fibro-osseous lesions of the craniofacial complex. Materials and methodsThis study included 25 patients. Their age ranged from 15 to 64years with a mean age of 37.56±15.17years. All the studied individuals were chosen selectively regarding complaint (those with known fibro-osseous lesions, facial disfigurement, and facial swelling) regardless of age and gender and examined using MDCT in detection of the lesion, and assessment of the extensions. ResultsIn the present study, the cranio-facial fibrous dysplasia represented almost half of the presented cases (48%) followed by osteomas (36%) then ossifying fibroma (12%) and brown tumor (4%). 13 out of 25 cases in this study were pathologically proven to be fibro-osseous lesions and surgically operated. The final diagnosis was made by consensus of imaging, clinical findings and pathological features. ConclusionsMulti-detector row CT images, including reformations, better delineate craniofacial complex anatomy than do single-detector row CT images. Using multi-slice CT scanning in the craniofacial complex becomes possible to depict the complete path of complex structures.

Role of Multidetector CT in Evaluation of Polytrauma Patients

The management of polytrauma is based on the principle that the care provided to trauma patients in the first few hours can be absolutely critical in terms of predicting long term recovery and that good trauma care involves getting the patient to right place in right time for the right treatment. Managing critically injured patients are challenging. It is very important to assess the overall severity in terms of site and extent of injury. Earlier radiographs, conventional CT scanners and focused assessment with sonography for trauma (FAST) used to be very useful adjuncts in management of polytrauma. Nowadays with the advent of state of art multidetector CT (MDCT) scanners the scenario has improved. Most of the centers dealing with trauma have a clear protocol of MDCT for management. There are concerns regarding cost, radiation and whether “CT first protocol” should be employed. Here we review the role of MDCT in assessment of patients with polytrauma and its current status.

Role of Multidetector CT in Evaluation of Acute Chest Pain: Non-Cardiac Vascular and Pulmonary Causes

Background: Triage of patients with acute chest pain is one of the most important issues currently facing physicians in the emergency department. Acute chest pain may be a symptom of a number of serious conditions and is generally considered a medical emergency. The causes of acute chest pain range from non-serious to life threatening. A rapid, accurate and cost-effective approach for the evaluation of emergency department patients with chest pain is needed. Aim of the work: This work aims to emphasize the role of multidetector CT in assessment of non-cardiac vascular and pulmonary causes of acute chest pain. Method: The studied group included 89 patients (59 men and 30 women) presented by acute chest pain. All patients were subjected to MDCT and/or MDCT angiography using a Toshiba 64 detectors CT scanner. Results: The high spatial resolution and relatively non-invasive nature make MSCT angiography a strong and serious competitor to established vascular imaging techniques. Having the additional ability to simultaneously acquire information on other organs, which enables the early diagnosis of complications. Conclusion: Continued technical improvements in acquisition speed and spatial resolution of computed tomography images, and development of more efficient image reconstruction algorithms which reduce patient exposure to radiation and contrast result in increased popularity of MDCT.
