Abstract:
Objective:Comparative analysis of imaging features of abdominal CT, B ultrasound and magnetic resonance cholangiopancreatography in three different methods for detection of extrahepatic bile duct stones. Methods: A random sample of extrahepatic bile duct stones were a sample of 150 cases as the object of study, patients in the endoscopic retrograde cholangiopancreatography after diagnosis, followed by B ultrasound examination, the implementation of CT scanning and MRI imaging in 142 cases, including 78 cases of B ultrasound detection, CT detection, 118 cases underwent MRI examination. Results: The detection results were recorded and compared the 3 imaging methods. Results: The positive rate of B ultrasound 39.4%, the positive rate of CT was 53.8%, MRI positive rate was 86.4%, the positive rate of MRI was significantly higher than that of B ultrasound and CT (x2=59.725, x2=25.595; P<0.01), the detection rate of CT was significantly higher than that of B ultrasound(x2=4.231, P<0.05). Diameter less than 8 mm of extrahepatic bile duct stones with B ultrasound and positive rate of 25%, the positive rate of CT was 33.3%, MRI positive rate was 60%, the positive rate of MRI was significantly higher than that of B ultrasound and CT(x2=7.789, x2=7.789;P<0.01), the detection rate of CT with no significant differences between the B ultrasound. Conclusion:MRI of extrahepatic bile duct stones with B ultrasound and the positive rate of CT is higher, but the clinical needs according to the comprehensive evaluation of individual patients, economic status, symptoms, diagnosis method for selecting suitable.
