MRCP结合轴位T2WI与CT对胰腺癌的诊断价值

The Value of MRCP Plus T2WI and CT in the Diagnosis and Assessment of Resectability in Pancreatic Cancer

目的 评价磁共振胰胆管成像(magnetic resonance cholangiopancreatography,MRCP)结合轴位T2加权图像 (T2WI)与CT两期增强诊断胰腺癌及评价其可切除性的准确性。方法 回顾性分析经手术和／或病理证实的胰腺 癌19例,术前均有MRCP及CT两期增强资料。根据图像资料进行诊断及评价胰腺癌的可切除性。结果 MRCP 结合轴位T2WI诊断阳性率为78．9％(15／19);CT两期增强扫描诊断阳性率为89．5％(17／19)。MRCP结合轴位 T2WI评价为可切除的3例,手术证实可切除的为2例;CT两期增强扫描诊断者评价可切除的为4例,手术证实可 切除为3例。结论 MRCP结合轴位T2WI与CT两期增强扫描对胰腺癌的诊断有相同的准确性,CT两期增强扫 描对胰腺癌可切除性评价优于MRCP结合轴位T2WI。

Objective To study the value of MRCP plus T2WI and CT in the diagnosis and assessment of resectability in pancreatic cancer. Methods MRCP plus T2WI and contrast-enhance CT were performed in 19 patients with pancreatic cancer. All the cases were proved by operation and/or pathology. By analyzing the imagings, the diagnosis of pancreatic cancer, and assessment of their resectability could be made. Results The positive rate of diagnosing pancreatic cancer by MRCP plus T2WI was 78.9% ; and that by contrast-enhance CT was 84.2%. 3 cases that could be resected were assessed by MRCP plus T2WI, and 2 cases were later resected by operation. There were 4 additional cases diagnosed by contrast-enhance CT,and 3 cases were later resected. Conclusion The results suggest that MRCP plus T2WI has the same veracity with contrast-enhance CT in diagnosing pancreatic cancer, and in assessing resectability, the latter seems to be better than the former.
