【摘要】 目的 :评价磁共振胰胆管成像 (MRCP)在胰胆管梗阻性病变诊断中的临床应用价值。方法 :对疑有胰胆管病变的 10 0例患者应用单次激发快速自旋回波 (SSFSE)厚层投射直接成像技术行MRCP检查。结果 :97例获得了优良的MRCP图像 ,MRCP可清晰显示各类胰胆管病变的形态异常 ;5 9例患者诊断为梗阻性胰胆管病变 ,其定位诊断准确率达 10 0 % ,定性诊断符合率为 83%。结论 :MRCP无创伤 ,无辐射 ,无需应用对比剂 ,是诊断胰胆管病变的理想方法 ,但对病变的定性诊断仍需结合常规MRI扫描及其它临床资料。更多还原

【Abstract】 Objective:To assess the clinical value of magnetic resonance cholangio pancreatography(MRCP) in diagnosis of pancreatic biliary tract obstructive diseases.Methods:From January to December of 2002,100 patients(42 men,58 women;age ranging from 31 to 74 years) suspected of pancreatic biliary tract obstructive diseases underwent conventional MR imaging and MRCP imaging with FSE sequence on a 1.5 T MRI scanner(GE Signa).Results:MRCP imaging was obtained successfully in 97 cases and 57 patients were diagnosed as pancreatic biliary tract obstructive diseases.The diagnostic accuracy in determining the location and the causes of the lesions was 100% and 83% respectively.Conclusions:MRCP imaging is an ideal method in diagnosis of pancreatic biliary tract obstructive diseases.It leaves no trauma,has no radiation and avoids the use of contrast agent.更多还原
