Assessment of magnetic resonance imaging derived fat fraction as a sensitive and reliable predictor of myosteatosis in liver transplant recipients.

Background: Measures of skeletal muscle abnormalities are rapidly emerging as independent predictors of outcomes after liver transplantation (LT). We describe a simple, novel assessment of myosteatosis acquired prior to liver transplantation using Magnetic Resonance Imaging (MRI) derived fat fraction.

Methods: A retrospective longitudinal cohort study included clinical and biochemical data from patients who underwent liver transplantation at our institution between Feb 2008 and Aug 2014.

Angiographic diagnosis of Meckel's diverticulum in an adult patient with negative scintigraphy.

A Meckel's diverticulum was diagnosed by mesenteric angiography in a 34 year-old patient who presented with hematochezia and dropping hemoglobin. The case demonstrates the challenges often encountered in workup of occult gastrointestinal (GI) bleeding, and shows that angiographic diagnosis of Meckel's diverticulum is possible, even in the absence of angiographic evidence of active extravasation. Our patient had a previous non-diagnostic workup including upper and lower endoscopy, videocapsulography, and Technetium-99m pertechnetate (Tc-99m) scintigraphy.
