Background: To evaluate the capability of a computed tomographic (CT) technique that combines distention of the small bowel loops with a transparent enema with contrast-enhanced spiral CT of the abdomen in patients with Crohn's disease. Methods: We evaluated the abdomen with spiral CT after distention of the small bowel loops with a transparent enema of(More)
A rare case of multiple bile duct hamartomas of the liver has been evaluated with ultrasound (US), computed tomography (CT), magnetic resonance imaging (MRI) and digital subtraction angiography (DSA). The CT and angiographic features of the hamartomas described here differ significantly from previously reported cases. In addition, the MR appearance of these(More)
Three normal volunteers and 20 patients with known Crohn's disease were examined with MRI--at 0.5 Tesla and with a superconductive magnet. Coronal T1-weighted GE images were mainly acquired, before and after i.v. Gd-DTPA injection in breath hold (TR 70 ms, TE 13 ms, FA 70 degrees). MR findings were compared with the results of small and large bowel enema.(More)
BACKGROUND The present study aimed to evaluate the added value of contrast-enhanced computed tomography (ceCT) in comparison to standard, non-enhanced CT in the context of a combined positron emission tomography (PET)/CT examination by means of a tumor-, site-, and clinical question-based approach. METHODS Analysis was performed in 202 patients undergoing(More)
Follow-up of Achilles tendon injuries was carried out by means of computerized telethermography. The thermographic examination was performed at definite time intervals (a few hours, 15 days, 1 month, 3 months after acute traumatism) on 15 young patients subdivided into two different groups according to the tenonic injured site: proximal (6 cases) or(More)
Spiral or helical technology is a new computed tomographic technique based on the continuous acquisition of volumetric CT data during continuous x-ray beam rotation and continuous patient transportation at constant velocity. It has many advantages over conventional CT: the authors briefly review the basic principles of spiral CT and discuss the applications(More)
The dilatation of the vascular grafts is a well known phenomenon. It is usually evaluated by means of ultrasounds or, in selected cases, by CT scans or MRI; nevertheless its characteristics are far beyond to be fully recognized. Following our promising preliminary experience with helical CT as sole preoperative imaging for AAA, we have evaluated its(More)
This article describes the sonographic appearance of a very common accessory fissure of the liver located on the inferior side of the left lobe. The fissure was recognized in about 5% of 800 consecutive subjects and showed variable appearance owing to different insertion levels on the inferior hepatic surface. It extended from the left hepatic border to the(More)
The reliability of helical CT as sole preoperative diagnostic technique for abdominal aortic aneurysms (AAA) and its accuracy in detecting vascular anomalies in the abdominal region was evaluated retrospectively in 42 patients with asymptomatic AAA > 40 mm. A single breath-holding helical scan was performed with 5 mm slice thickness, during a single(More)
