磁共振胰胆管成像诊断胆系梗阻性疾病的临床评价

目的　探讨磁共振胰胆管成像 (MRCP)对胆道梗阻性疾病的临床诊断价值。方法　对 42例胆道梗阻患者进行MRCP检查 ,并经手术病理或 /和其它影像学和临床资料证实。结果　①本组MRCP定位诊断率为 10 0 % ,定性准确率为 83 % ;②扩张的胆道表现为枯枝状 2 3例、软藤状 15例、腊肠样 4例 ;③梗阻端呈倒杯口状 6例、截断状 5例、杵状 17例、鸟嘴状 9例、鼠尾状 5例。结论　MRCP对胆道梗阻性疾病定位诊断准确 ,结合MRI及源像对胆道梗阻性疾病的定性诊断也具有较高的特异性 ,是一种安全快捷、非创伤性的检查方法 ,能为胆道梗阻的诊治及术后评估提供可靠的依据。

MR Cholangiopancreatography for Diagnosis of Biliary Obstructive Disease

Objective To evaluate the clinical diagnositic value of biliary obstructive disease by magnetic resonance cholangiopancreatography (MRCP).Methods 42 patients with biliary obstructive disease confirmed by operation and pathology or other imagilogic examination and clinic data were examined by MRCP. Results Diagnostic rate of MRCP for obstructive level was 100%,the specificity for the cause of obstruction was about 83.0%. The dilated biliary ducts appeared"withered tree branches-like" in 23 cases,"soft canes-like" in 15 cases ,"sausage-like" in 4 cases.The obstructive ends exhibited"down cup mouth-form"in 6 cases,"cut off-form"in 5 cases,"club-form" in 17 cases,"bird mouth-form"in 9 cases,"mousetail-form" in 5 cases. Conclusion MRCP can accurately define the obstructive site in biliary obstructive disease, the specificity for diagnosis of biliary obstruction is very high when combining with MRI and resource images. It is a safe, quick and noninvasive effective imagilogic examination, it is reliable for confirming the diagnosis and treatment as well as post-operative evaluation of the biliary obstructive disease.
