The Diagnostic Value of MR Cholangiopancreatography in Gallstones / 天津医药

ABSTRACT

Objective: To evaluate the diagnostic value of magnetic resonance cholangiopancreatography (MRCP) in gallstones.Methods: Seventy-three patients with gallstones were examined with MRCP. Results: MRCP showed the lesions directly in69 patients,of which 58 patients were proved by surgery. The characteristic imaging appearance included a round,oval ormultifaceted area of filling defect and crateriform depression within the lumen of the bile ducts. MRCP could show false-positive result caused by air within the bile ducts. In the other 4 patients with tiny intra-hepatic stones ( ＜4 mm) ,MRCP couldnot show the lesions except for the proximal bile duct dilation. Conclusion:MRCP is a safe,non-invasive and reliable examination and may act as substitute method for patients unsuitable for endoscopic retrograde cholangiopancreatography (ER-CP).
