Radiopaque biodegradable stent for duct-to-duct biliary reconstruction in pigs.

Background: Biliary stricture is a common cause of morbidity after liver transplantation. We previously developed a duct-to-duct biliary anastomosis technique using a biodegradable stent tube and confirmed the feasibility and safety of biliary stent use. However, the duration and mechanism of biliary stent absorption in the common bile duct remain unclear.

Differential diagnosis of hepatic tumor-like lesions in dog by using dynamic CT scanning.

Dynamic liver CT scanning is used to observe the hemodynamics of hepatic tumor-like lesions by taking images sequentially after administration of contrast media. In this study in dogs, we compared the hemodynamic patterns of hepatocellular carcinoma (HCC), one of the malignant tumors, and nodular hyperplasia (NH), a benign tumor that is more common in older dogs. Thirty-six dogs with HCC and 40 dogs with NH, which were histopathologically diagnosed at Taniura Animal Hospital, were used as subjects.

The use of multi-detector row computed tomography (MDCT) as an alternative to specimen preparation for anatomical instruction.

The purpose of the study reported here was to establish a method of teaching veterinary anatomy, including radiologic anatomy, for clinical practice using computer-aided diagnosis (CAD). Two clinically healthy dogs and three cats were scanned using multi-detector row computed tomography (MDCT). Images were made by means of imaging processing software.
