[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.

Oral distension methods for small bowel MRI: comparison of different agents to optimize bowel distension.

Background Different methods for bowel distension prior to magnetic resonance imaging (MRI) examinations were described in recent years. Purpose To compare orally administered psyllium or locust bean gum / mannitol (LBM) with tylose administered through a duodenal catheter for bowel distension in patients undergoing MRI examination of the small bowel. Material and Methods Three different methods of bowel distension prior to MRI were compared: tylose applied through a duodenal catheter and orally administered psyllium and LBM in three groups with 15 patients each.

[S3 guideline--Diagnosis and treatment of colorectal carcinoma: relevance for radiologic imaging and interventions].

The new German S3 guideline "Colorectal Carcinoma" was created as part of the German Guideline Program in Oncology of the Association of the Scientific Medical Societies in Germany, the German Cancer Society and the German Cancer Aid under the auspices of the German Society for Digestive and Metabolic Diseases and replaces the guideline from 2008. With its evidence-based treatment recommendations, the guideline contains numerous updates and detailed definitions regarding the diagnosis and treatment of colon and rectal cancer. In particular, consensus-based recommendations regarding early detection, preoperative diagnostic method selection, and the use of interventional radiological treatment methods are detailed.

Characteristics, changes and influence of body composition during a 4486 km transcontinental ultramarathon: results from the TransEurope FootRace mobile whole body MRI-project.

Background: Almost nothing is known about the medical aspects of runners doing a transcontinental ultramarathon over several weeks. The results of differentiated measurements of changes in body composition during the Transeurope Footrace 2009 using a mobile whole body magnetic resonance (MR) imager are presented and the proposed influence of visceral and somatic adipose and lean tissue distribution on performance tested.

Methods: 22 participants were randomly selected for the repeated MR measurements (intervals: 800 km) with a 1.

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.
