MRI can assess glenoid bone loss after shoulder luxation: inter- and intra-individual comparison with CT.

Objective: Computed tomography (CT) is the gold standard for evaluating glenoid bone loss in patients with glenohumeral dislocations. The aim of this study was to verify if magnetic resonance imaging (MRI) can quantify the area of bone loss without any significant difference from CT.

Materials And Methods: Twenty-three patients, who had experienced one or more post-traumatic unilateral glenohumeral dislocations, underwent MRI and CT.

Contrast-bolus MR angiography of the transplanted kidney with a low-field (0.5-T) scanner: diagnostic accuracy, sensitivity and specificity of images and reconstructions in the evaluation of vascular complications.

Purpose: This study was performed to assess the feasibility, interobserver variability, sensitivity, specificity and diagnostic accuracy of raw data and postprocessed images from a low-field (0.5-T) magnetic resonance (MR) unit in evaluating vascular complications of kidney grafts.

Materials And Methods: We enrolled 49 patients undergoing MR angiography (MRA) for a clinical suspicion of renal artery stenosis.

[Intraluminal ultrasonography of the biliary ducts].

We report our 4 years' experience with intraluminal US of the biliary ducts performed on 24 patients via a biliary transhepatic-duodenal drainage catheter or a surgically inserted T tube (2 cases). The final diagnosis was a malignant disease in 16 patients and a benign disease in 8 patients. We used an Intra Vascular Ultra Sound (Diasonics) unit with a 20 MHz transducer inserted into a 9 F catheter with closed tip, which in turn was pushed through the biliary ducts in a 12 F sheathed introducer which provides a safety metal guide wire in the duodenum.
