A 77-year-old man underwent endoscopic submucosal dissection (ESD) of a type 0-IIc tumor located in the cardiac part of the stomach. The pathological diagnosis of the tumor was poorly differentiated tubular adenocarcinoma with submucosal invasion dep

Publikováno v: Journal of Ultrasound in Medicine. 22:365-373

Objective. We investigated whether an ultrasonic echo contrast agent containing microbubbles (Levovist [SH U 508A]; Schering AG, Berlin, Germany) could in routine use activate platelets. Methods. Levovist and its main component, galactose, were mixed

Publikováno v: Journal of ultrasound in medicine : official journal of the American Institute of Ultrasound in Medicine. 24(7)

OBJECTIVE The purpose of this study was to compare platelet activation and hepatic cell damage produced by 2 ultrasonographic contrast agents with flow cytometric and ultrastructural analysis. METHODS Suspension samples were made by mixing Levovist (

Publikováno v: Journal of ultrasound in medicine : official journal of the American Institute of Ultrasound in Medicine. 23(1)

Objective. To determine whether contrast ultrasonography can affect the sinusoidal cells and platelets of the liver by using ultrastructural analysis in vivo. Methods. Fifteen Wistar rats were placed into the following 5 groups of 3 rats each: 3 cont

Ultrasonographic evaluation using the internal echo in normal and cirrhotic livers: Comparison of accuracy of gray-scale and binary black-and-white images and their intraobserver reproducibility and interobserver agreement

Autor: Kouichi Itoh, Nobuyuki Taniguchi, Kouichirou Shigeta, Yasutomo Fujii, Iwaki Akiyama, Yi Wang, Kiyoka Omoto

Publikováno v: Journal of medical ultrasonics (2001). 30(1)

We attempt to determine the possibility of classifying normal and cirrhotic livers by their internal echo texture alone, without using such basic ultrasonographic information as shape and surface character of the liver. We also assessed intraobserver
