腔内增强超声 (CEUS) 显著提高胆道梗阻诊断准确率

Intrahepatic bile ducts of first order and above; hepatic duct; common bile duct and below. This is a set of research data from our previous study. In this table, we can find that compared with conventional ultrasound, intraoperative contrast-enhanced ultrasound (CEUS) significantly improves the diagnostic ability for obstructive sites in the bile duct, especially for obstructions of the hepatic duct and above, with an accuracy rate of 100%.
