Miniaturization of ultrasound probes has made possible endoluminal investigation of small duct systems. We have used a 360° transaxial real-time sector-scan imaging system with a field of view of 3–5 cm. It operates at ultra-high frequencies, which allows very high resolution. Ten jaundiced patients, aged 35–73 years, were investigated. Malignant bile-duct obstructive disease was present in eight and benign strictures in the remaining two. In all of them the intrahepatic bile ducts had… CONTINUE READING
