[Percutaneous paraumbilical embolization of bleeding rectal varices due to portal hypertension].

 Portal hypertension may lead to severe esophageal or rectal variceal bleeding.  We present a case of a 67-year-old patient presenting with recurrent rectal variceal bleeding who was non-responsive to endoscopic treatment. We are reporting on an interventional therapeutic approach found in interdisciplinary consensus.

Early detection of temporomandibular joint arthritis in children with juvenile idiopathic arthritis - the role of contrast-enhanced MRI.

Background: Early treatment of temporomandibular joint (TMJ) arthritis is crucial in children with juvenile idiopathic arthritis (JIA) to prevent permanent functional impairment. As involvement of TMJs is often asymptomatic, contrast-enhanced MRI is regarded as the most sensitive noninvasive diagnostic tool.

Objective: To evaluate the degree of contrast enhancement in TMJs of children and adolescents with JIA in comparison to normal controls from a previous study.

Contrast-enhanced MRI of normal temporomandibular joints in children--is there enhancement or not?

Objectives: To determine the degree of contrast enhancement of normal TM joint (TMJ) in children and to provide reference data for patients with JIA.

Methods: A total of 100 dynamic contrast-enhanced MRI of 46 children from 1.6 to 18 years (median 9.

Sixty-four MDCT achieves higher contrast in pancreas with optimization of scan time delay.

Aim: To compare different multidetector computed tomography (MDCT) protocols to optimize pancreatic contrast enhancement.

Methods: Forty consecutive patients underwent contrast-enhanced biphasic MDCT (arterial and portal-venous phase) using a 64-slice MDCT. In 20 patients, the scan protocol was adapted from a previously used 40-channel MDCT scanner with arterial phase scanning initiated 11.

Prospectively gated axial CT coronary angiography: comparison of image quality and effective radiation dose between 64- and 256-slice CT.

Purpose: To compare image quality and effective radiation dose for prospectively gated axial CT coronary angiography on 64- and 256-slice CT.

Methods: The patient cohort consisted of 80 consecutive patients undergoing imaging with 256-slice CT and 80 patients with 64-slice CT. The two patient groups were demographically matched according to age, gender, body mass index and heart rate.

Pitfalls in abdominal diffusion-weighted imaging: how predictive is restricted water diffusion for malignancy.

Objective: As diffusion-weighted imaging is increasingly implemented into routine protocols of abdominal MRI, abnormal findings in expected and unexpected locations become more common. The aim of our retrospective study was to investigate the specificity of restricted diffusion in differentiation of benign from malignant abdominal disease.

Materials And Methods: Two hundred thirty consecutively registered patients underwent abdominal MRI including diffusion-weighted imaging (single-shot spin-echo echo-planar sequence) with b values of 0, 150, 500, and 1,000 s/mm(2).
