Abstract:
Objective To investigate the feasibility and methodology of detecting the microcirculation of hilar bile duct wall with contrast-enhanced ultrasound (CEUS). Methods Sixteen patients after orthotropic liver transplantation(OLT) were studied. The dosage of contrast agent(SonoVue) was set for 2 groups: 1.5 ml and 2.4 ml. Each group was composed of 8 patients. The imaging quality of CEUS were retrospectively analyzed and divided into 3 grades: good, ordinary and bad. There were 2 patients received retransplantation. Their morphologic features of hilar bile duct wall in baseline ultrasound (US) and CEUS were compared with those in pathological examination. Results Biliary perfusion could be displayed by CEUS continuously,real-timely and clearly. The imaging quality was good in 8 cases(50%), ordinary in 6 cases (37. 5%) and bad in 2 cases(12. 5%). There was no significant difference between the imaging quality of 1. 5 ml and that of 2. 4 ml group ( P = 0. 78). Conclusions The imaging quality of hilar bile duct wall in CEUS is good enough to detect its microcirculation. There is no significant difference between the imaging quality of 1. 5 ml and that of 2.4 ml group.
