PURPOSE To determine the sensitivity of magnetic resonance (MR)-enterography for the detection of neuroendocrine tumors of the small-bowel (NETSB) and analyze the imaging presentation of NETSB on MR-enterography. PATIENTS & METHODS The MR-enterography studies (including HASTE, TruFISP, and 3D VIBE MR sequences before and after intravenous administration(More)
Postpartum hemorrhage (PPH) is a potentially life-threatening condition, which needs multidisciplinary management. Uterine atony represents up to 80 % of all causes of PPH. Transcatheter arterial embolization (TAE) has now a well-established role in the management of severe PPH. TAE allows stopping the bleeding in 90 % of women with severe PHH, obviating(More)
OBJECTIVE To qualitatively and quantitatively analyze the presentation of intrahepatic and hilar mass-forming cholangiocarcinoma with diffusion-weighted magnetic resonance imaging (DW-MRI). MATERIALS AND METHODS Twenty-eight patients with histopathologically proven mass-forming cholangiocarcinoma (hilar, n=17; intrahepatic, n=11) underwent hepatic DW-MRI(More)
To assess the role and effectiveness of percutaneous arterial embolization (TAE) in patients with hemodynamic instability due to hypovolemic shock secondary to ruptured splanchnic artery pseudoaneurysms (SAPA). Seventeen patients (11 men, 6 women; mean age, 53 years) with hemodynamic instability (systolic blood pressure <90 mmHg) due to hypovolemic shock(More)
Uterine myometrial tumors are predominantly benign conditions that affect one-third of women and represent the main indication for hysterectomy. Preoperative imaging is of utmost importance for characterization and for precise mapping of myometrial tumors to best guide therapeutic strategy. New minimally invasive therapeutic strategies including(More)
To test whether variations in apparent diffusion coefficient (ADC) values of uterine leiomyomas after uterine artery embolization (UAE) may correlate with outcome and assess the effects of UAE on leiomyomas and normal myometrium with magnetic resonance imaging (MRI). Data of 49 women who underwent pelvic MRI before and after UAE were retrospectively(More)
Recent refinements in cross-sectional imaging have dramatically modified the investigation of the jejunum. Improvements in multidetector row computed tomography (MDCT) and magnetic resonance (MR) imaging technology have made detection and characterization of jejunal abnormalities easier. Current options include MDCT and MR imaging using either enterography(More)

PURPOSE To investigate the possible relationships between sigmoid diverticula, the volume of the left lateral segment of the liver and sigmoid colon volvulus. MATERIAL AND METHODS The presence of sigmoid diverticula was analyzed in 36 patients (24 men, 12 women; mean age, 70.77±19.86 [SD] years) with sigmoid volvulus (group 1). The volumes of left lateral(More)
