Multiple Esophageal Squamous Papillomas.

We report a rare case of multiple esophageal squamous papillomas (ESPs). A 42-year-old man underwent a medical examination, and abnormalities of multiple elevated lesions were noted using a esophagogastroduodenoscope. He underwent upper gastrointestinal tract radiography with an orally ingested barium sulfate and gastrointestinal endoscopy, which revealed multiple elevated lesions in the esophagus, predominantly on the distal esophagus.

Obliteration of the Biliary System after Administration of an Oral Contrast Medium Is Probably due to Regurgitation: A Pitfall on MRCP.

Purpose: We retrospectively evaluated the incidence and related factors of obliteration of the lower bile duct after oral administration of contrast medium (OCM) probably resulting from its regurgitation into the biliary system (OCMRB) as observed on images of MR cholangiopancreatography (MRCP).

Methods: We retrospectively analyzed 305 MRCP images in 278 patients obtained between February 2010 and March 2011 using negative OCM with 1.0- and 1.

Measurement consistency of MR elastography at 3.0 T: comparison among three different region-of-interest placement methods.

Purpose: To test inter- and intraobserver consistency of liver stiffness measurement on MR elastography (MRE) at 3.0 T.

Materials And Methods: Two abdominal radiologists independently measured stiffness of the liver on MRE in three volunteers and seven patients with chronic liver diseases using three different region-of-interest (ROI) placement methods.
