Three-dimensional computed tomography rendering of pedunculated colon polyp: new "clapper-bell" sign pedunculated polyp at 3D computed tomography.

The incidental detection of a tubulovillous adenoma at a contrast-enhanced computed tomography (CECT) with nondedicated protocol, performed in emergency conditions, is an uncommon finding. We report a case of a woman presenting with a subocclusive episode. A CECT scan was performed, and a pedunculated polyp could be appreciated at 3D-reconstruction images.

Megacolon for a giant faecaloma with unlucky outcome: case report and review of the literature.

We herein report a case of megacolon with fecaloma in an 83-year-old man who presented with constipation, no intestinal occlusion, and a left hydroureteronephrosis, with A.S.A.

New type of asymptomatic congenital portosystemic shunt.

Congenital extrahepatic portosystemic shunt (CEPS) is an extremely rare anomaly. In these malformations splanchnic blood bypasses the liver and drains into the systemic circulation through the inferior vena cava (IVC) or the left renal vein (LRV). Extrahepatic shunts may be divided into type 1 [end-to-side mesenterico-caval fistula with congenital absence of the portal vein (PV)] and type 2 (partial portocaval shunt caused by side-to-side mesenterico-caval fistula with normal or hypoplasic PV).

Multiparameter characterisation of vertebral osteoporosis with 3-T MR.

Purpose: This study was undertaken to evaluate the diagnostic capabilities of 3-Tesla (T) magnetic resonance (MR) in vertebral osteoporosis.

Materials And Methods: Thirty subjects (ten healthy controls, ten with osteoporosis but no fracture, ten with osteoporotic vertebral fractures) underwent MR of the lumbar spine. Turbo spin echo (TSE) T1-, T2- and T2- spectral selection attenuated inversion recovery (SPAIR) weighted imaging and spectroscopy for the selective evaluation of water and fat content were performed.

Integrated multislice CT and Tc-99m Sestamibi SPECT-CT evaluation of solitary pulmonary nodules.

Purpose: The purpose of this study was to evaluate efficacy of multislice computed tomography (MSCT) and single photon emission computed tomography (SPECT)-CT with Tc-99m Sestamibi in the assessment of solitary pulmonary nodules of uncertain significance. Scintigraphy was performed using a 'hybrid' g-camera that allows simultaneous acquisition of SPECT and CT images, with interesting results in diagnostic oncology.

Materials And Methods: Between September 2003 and August 2004, 23 patients with a solitary pulmonary nodule detected on CT underwent SPECT-CT using Tc-99m Sestamibi as a radiotracer.
