OBJECTIVE Though a number of CT findings of bowel and mesenteric injuries in blunt abdominal trauma are described in literature, no studies on the specific CT signs of a transected bowel have been published. In the present study we describe the incidence and new CT signs of bowel transection in blunt abdominal trauma. MATERIALS AND METHODS We investigated(More)
Primary liposarcoma of the liver is extremely rare. We report here on a case of primary well-differentiated liposarcoma in the left hepatic lobe of a 63-year-old woman. Abdominal ultrasonography showed a well-defined, echogenic, round mass. Abdominal computed tomography (CT) and magnetic resonance (MR) images showed an almost fatty, lobulated mass with a(More)
PURPOSE To compare the diagnostic performance of gadoxetic acid-enhanced MRI with that of multi-phase 40- or 64-multidetector row computed tomography (MDCT) to evaluate viable tumors of hepatocellular carcinomas (HCCs) treated with image-guided tumor therapy. MATERIALS AND METHODS A total of 108 patients with 162 HCCs (56 lesions with viable tumor and 106(More)
PURPOSE To determine the optimal surface-rendering threshold value for three-dimensional (3D) endoluminal computed tomographic (CT) colonographic images for accurate manual polyp measurement, with direct measurement of simulated polyps as the reference standard, and to assess the agreement between manual 3D measurements and automated measurements.

Perineurioma is an unusual benign peripheral nerve sheath tumor that includes intraneural, soft tissue (conventional), reticular and sclerosing types. Sclerosing perineurioma is a recently described distinctive variant occurring nearly exclusively on the hands of young adults, in which it presents as a small, painless, dermal or subcutaneous mass. The only(More)
OBJECTIVE To determine the diagnostic accuracy of combined magnetic resonance cholangiopancreatography (MRCP) and computed tomography (CT) for preoperative diagnosis of Mirizzi syndrome. MATERIALS AND METHODS Fifty-two patients with surgically proven Mirizzi syndrome (n = 13) and cholecystitis without evidence for Mirizzi syndrome (n = 39) underwent both(More)
To evaluate the feasibility of ultrasound in detecting spontaneous pneumomediastinum in the neonatal intensive care unit (NICU) and illustrate the ultrasound features. Among neonates with abnormal mediastinal radiolucency suspected on chest radiography, those referred for ultrasound examination within 2 days were included. Anterior mediastinal ultrasound(More)
Immunoglobulin G4 (IgG4)-related sclerosing disease is rare and is known to involve various organs. We present a case of histologically proven IgG4-related sclerosing disease of the small bowel with imaging findings on computed tomography (CT) and small bowel series. CT showed irregular wall thickening, loss of mural stratification and aneurysmal dilatation(More)
