Abstract

Purpose To explore the application value of contrast agent in non-vascular channel. Material and Methods Totally 68 patients with drainage tube/stoma were collected in the pattern of real-time contrast enhanced ultrasound. Position, scope and moving of contrast agent in non-vascular channel were observed. Results It was accurately revealed enhanced areas in 68 cases of drainage tube and stoma, including 9 abnormal cases. CEUS implied 3 cases of failed drainage ifrstly, 5 cases of bleeding and 1 case gallbladder stone. It judged the degree and location in 25 PTBD cases and 22 PCN cases. The distance with renal hilum of one parapelvic cyst was measured accurately. Conclusion It is very important in diagnosis and treatment of interventional ultrasound to CEUS, therefore is worthy of wide application.
