In this series a pictorial quiz pertaining to identification of normal anatomical structures and landmarks at a given level on the computed tomography (CT) is presented. An image depicting normal anatomy is followed by a series of images showing different pathologies. Readers are expected to identify and appreciate variation and changes in the normal anatomy in presence of a given pathology. Th...

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...

we report a three-phase bone scintigraphy for the diagnosis of a peripheral bone lesion caused by systemic sarcoidosis. a 32-year-old man with suspected osteomyelitis of the right forefinger underwent three-phase bone scintigraphy with tc-99m hydroxymethylene diphosphonate (hmdp) and single-photon emission computed tomography/computed tomography (spect/ct). the lesion was rich in blood flow acc...

conclusion ct scan is highly accurate in differentiating malignant pleural mesothelioma and metastatic pleural diseases. pleural thickening and thickening of interlobar fissure lead us to the diagnosis of mpm and massive free pleural effusion is more commonly seen in metastatic pleural malignancy. background malignant pleural mesothelioma (mpm) is a rare malignant neoplasm of the pleura that ty...

mediastinal teratomas are usually asymptomatic tumors, located most commonly in the anterior mediastinum. very rarely, such tumors may rupture into the tracheobronchial tree, lung, pleura or pericardium. computed tomography (ct) is helpful in the diagnosis and differentiation of ruptured and unruptured tumors. we report a case of ruptured anterior mediastinal teratoma in a 20-year-old female pr...

conclusions both eps and er residents either missed or falsely called a significant number of pathologies in their interpretations. the interpretations of eps and er residents were more sensitive and more specific, respectively. these findings revealed the need for increased training time in head ct reading for residents and the necessity of attending continuing medical education workshops for ...

introduction: motion artifacts are a common problem in pediatric radiographic studies and are a common indication for pediatric procedural sedation. this study aimed to compare the combination of oral midazolam and ketamine (omk) with oral midazolam alone (om) as procedural sedatives among children undergoing computed tomography (ct) imaging. methods: the study population was comprised of six-m...

in the present study application of x-ray computed tomography as a nondestructive technique for estimation of some qualitative parameters of pomegranate fruit was studied. for this purpose, three local cultivars of pomegranate fruit of fars province, iran that included; rabab malas, rabab torsh and khani kazeroon were used. the x-ray ct images of pomegranate fruits were prepared using ct-scan d...
