Introduction: The Republic of Korea has developed a national standard based on which diagnostic X-ray equipment must be tested every 3 years. Accordingly, the performance of X-ray equipment used in all hospitals is evaluated by national certification bodies in compliance with the safety management regulations for X-ray equipment. However, if the equipment i...

AIM Extranodal mucosa-associated lymphoid tissue (MALT) arises a number of epithelial tissues, including the stomach, salivary gland, lung, small bowel, and elsewhere. Here we present a male patient with an uncommon site of extranodal MALT such as a pelvic mass diagnosed after a long period of evaluation, which initially presented with an incidental pulmonary nodule. METHOD We report a 60 yea...

Pediatric pelvic injury is of major significance despite these injuries in children are rare with a suspected yearly rate of 3% of all pelvic injuries. The special pediatric bone anatomy of the pelvis is responsible for different fracture patterns, and overall, a bony or joint injury of the pelvis is an indicator of a severe trauma. The vast majority of pediatric pelvic fractures is the result ...

methods retrospective cohort study of blunt trauma patients with rib fractures at a level i trauma center that had both a cxr and a ct chest. the ct finding of ≥ 3 additional fractures in patients with ≤ 3 rib fractures on cxr was considered clinically meaningful. student’s t-test and chi-square analysis were used for comparison. results we identified 499 patients with rib fractures: 93 (18.6%)...

background: bisphosphonates (bps) are used extensively for managing the osteoporosis. there are some controversies on atypical fractures of femur that associated with increase in cortical thickness (ct) and bps' use. in this study, the effects of alendronate consumption were studied on femoral ct as a predictor for atypical fracture.   methods: forty nine post-menopausal women aged 50-70 years ...

A 46-year-old man presented with a 2-day history of abdominal pain, nausea and vomiting. The abdomen was diffusely tender, and the bowel sounds were sluggish. Chest/ abdominal radiographs (Picture 1, 2) and abdominal/pelvic computed tomography (CT) were performed (Picture 3). Chilaiditi syndrome is the interposition of the right colon between the liver and right hemi-diaphragm; the bowels conta...

clay minerals are considered the most important components of clastic reservoir rock evaluation studies. the shurijeh gas reservoir formation, represented by shaly sandstones of the late jurassic-early cretaceous age, is the main reservoir rock in the eastern kopet-dagh sedimentary basin, ne iran. in this study, x-ray diffraction (xrd), x-ray fluorescence (xrf), scanning electron microscopic (s...

Introduction: Crosstalk is a leakage of X-ray or light produced in a matrix of X-ray detectors or array of photodiodes in one element to other elements affecting on image contrast and spatial resolution. In this study, we assessed X-ray crosstalk in a computed tomography (CT) scanner with small detector elements to estimate the effect of various parameters such as X-ray tube voltage, detector e...
