Outflow of N-butyl-2-cyanoacrylate into the Pancreatic Duct: Transcatheter Arterial Embolization for Hemosuccus Pancreaticus.

A 54-year-old Japanese woman, hospitalized for recurrent chronic alcoholic pancreatitis, manifested bloody stools. An esophagogastroduodenoscopy revealed active bleeding from the papilla of Vater. Contrast-enhanced computed tomography (CECT) revealed a pseudoaneurysm in the pancreatic pseudocyst (hemosuccus pancreaticus).

Optimization of the uptake method for estimating renal clearance of 99mTc mercaptoacetyltriglycine.

Objective: To improve the estimation of 99mTc mercaptoacetyltriglycine clearance in the renal uptake method by optimizing the conditions of renal depth, background, threshold for renal boundary determination, and time interval for integrating renal counts.

Methods: Dynamic renal imaging was performed in 232 patients with dual energy window acquisition (main, 140 +/- 14keV; sub, 122.5 3.
