conclusion according to our findings, ct-guided percutaneous drainage is a safe and effective procedure in the treatment of abdominal abscess and fluid collection. results the average age of the patients was 54 years (range 12 to 79), including 21 (51%) men and 20 (49%) women. the common signs and symptoms were pain (83%) and fever (80.5%). the most prevalent abdominal abscess etiology was prev...

Background: Medical X-rays are the largest man-made source of public exposure to ionizing radiation. While the benefits of Computed Tomography (CT) are well known in accurate diagnosis, those benefits are not risk-free. CT is a device with higher patient dose in comparison with other conventional radiation procedures. Objective: This study is aimed at evaluating radiation dose to patients from ...

ABSTRACTNeuroimaging allows noninvasive evaluation of the anatomy, physiology, and function of the brain. It is widely used for diagnosis, treatment planning, and treatment evaluation of neurological disorders as well as understanding functions of the brain in health and disease. Neuroimaging modalities include X-ray computed tomography (CT), magnetic resonance imaging (MRI), single photon emis...

abstract necrotizing sarcoid granulomatosis (nsg) is a rare disease which is classified in the spectrum of pulmonary angiitis and granulomatosis. it is a variant of sarcoidosis and differs from it histologically. diagnosis is based on the pathological features, but radiology may help in the differential diagnosis. it is characterized by alveolar infiltrates or parenchymal nodules in multidetect...

This mage based series comprises of a quiz pertaining to the identification of salient anatomical structures expected to be seen at a given level on the computed tomography (CT) followed by examples of multiple representative pathologies that can be seen at the same level in a routine clinical setting. It is expected that this will improve confidence of nuclear physicians in interpretation of t...

background coronary artery anomalies are not common, but could be very serious. objectives this study determines the frequency of coronary anomalies and normal variants by multi-detector-row computed tomography (mdct). patients and methods the results of cardiac mdct study in 2697 consecutive patients were analyzed retrospectively. acquisition was performed by a 64-detector row ct machine. imag...

plagiocephaly (oblique skull) is premature fusion of one of the coronal sutures. frontal plagiocephaly is a rare congenital deformity in the skull that is the most complicated form of craniosynostosis to treat. examination of all sutures is necessary for diagnosis of craniosynostosis in this article, a 10-month-old, healthy girl with deformity of the right forehead and orbit that is caused by f...

conclusions headache, seizure, and trauma are the main reasons for ct scan requests. about 12% of the brain ct scans were abnormal. being knowledgeable about the indications of imaging, unnecessary imaging can be prevented, and consequently, its risks can be minimized. patients and methods in the present case series, demographic information and ct scan reports of 167 patients referred to taba r...

osteoma is a benign, slow-growing osteogenic tumor that sometimes arises from the craniomaxillofacial region, such as the sinus, temporal or jaw bones. osteoma consists of compact or cancellous bone that may be peripheral, central or extraskeletal type. peripheral osteoma arises from the periosteum and is commonly a unilateral, pedunculated mushroom-like mass. peripheral osteoma of the mandible...
