Contrast Research Of Different Imaging Diagnosis Methods On Obstructive Jaundice

Objective:To evaluate the application of ultrasound, CT, MRCP, ERCP and PTC in obstructive jaundice.Methods: Patients diagnosed as obstructive jaundice from Jan 2003 to Nov 2009 were included in this study. The indication ratio of every method was calculated and compared.Results: 473 patients were included, and the indication ratio of ultrasound, CT, MRCP, ERCP and PTC in obstructive jaundice was 59.6%(257/431),80.9%(106/131),88.8%(326/367),84.2%(64/76),100%(31/31), and there are fifteen diseases in these patients.Conclution: Every method has its own advantages and disadvantages. MRCP is better than others. However, MRCP has limited specificity for diagnosis, so that more tests are still required when necessary.
