磁共振胰胆管成像临床应用的价值初探

Clinical application value of MR cholangiopancreatography

目的探讨磁共振胰胆管成像(MRCP)的临床应用价值。方法采用重T2加权单次激发对98例临床诊断胆道梗阻性疾病和拟诊胰胆疾病患者进行MRCP检查,并经手术病理或其他影像学和临床资料证实。结果恶性梗阻28例,其中胆管癌12例、胰头癌8例、壶腹癌5例、原发性肝细胞癌直接侵犯3例,良性梗阻70例、胆总管结石30例、胆囊切除术后狭窄9例,其他、胆囊炎或结石25例、慢性胰腺炎6例,本组定位诊断率为100.0%,定性准确率为87.7%。结论MRCP对胆道梗阻性疾病定位较为准确,结合MRI轴位、冠状位原始图像,对胆道梗阻性疾病的定性诊断也有较高的特异性,是一种安全、非创伤的检查方法,能为胆道梗阻性疾病诊治提供可靠的依据。

Objective: To assess the clinical application value of MR cholangiopancreatography (MRCP). Methods: In 98 cases, heavily T2-Weighted Haste (half-fourier acquisition single-shot turbo-Se) The clinical diagnostic biliary obstructive disease and had doubt pancreatic and bile diseases were examination by MRCP. By operation and pathology or other imagilogic examination and clinic data were examined by MRCP. Results: Diagnosis rate of MRCP for obstructive level was 100.0%. The specificity for the cause of obstruction was about 87.7%. Conclusions: 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 safe, noninvasive effective imagilogic examination, it is reliable for confirming. The diagnosis and treatment as well as of the biliary obstructive disease.
