Prostate cancer heterogeneity: texture analysis score based on multiple magnetic resonance imaging sequences for detection, stratification and selection of lesions at time of biopsy.

Objective: To undertake an early proof-of-concept study on a novel, semi-automated texture-based scoring system in order to enhance the association between magnetic resonance imaging (MRI) lesions and clinically significant prostate cancer (SPCa).

Patients And Methods: With ethics approval, 536 imaging volumes were generated from 20 consecutive patients who underwent multiparametric MRI (mpMRI) at time of biopsy. Volumes of interest (VOIs) included zonal anatomy segmentation and suspicious MRI lesions for cancer (Likert Scale score >2).

Embolization of peripheral high-flow arteriovenous malformations with Onyx.

Purpose: The aim of this study was to report our experience in embolization of high flow peripheral arteriovenous malformations (AVMs) with Onyx.

Material And Methods: Nineteen patients (10 men, 9 women) with peripheral high-flow AVMs who were treated with arteruial embolization using Onyx were retrospectively included. AVMs were located in the head and neck (6), extremities (5), chest (2), kidney (2), uterus (2), pelvis (1) and parietal (1).

Transjugular intrahepatic portosystemic shunt placement increases feasibility of colorectal surgery in cirrhotic patients with severe portal hypertension.

Background: Colorectal resection in cirrhotic patients is associated with high mortality and morbidity related to portal hypertension and liver insufficiency.

Methods: This retrospective study evaluated the clinical outcomes of cirrhotic patients who underwent transjugular intrahepatic porto-systemic shunt (TIPS) placement before colorectal resection for cancer. Main outcomes measures were postoperative morbidity and mortality rates.
