低张力MRI与内窥镜对照评价十二指肠乳头区的研究

A comparative study of hypotonic MRI and endoscopy in evaluation of the duodenal papillary region

目的探讨ＭＲＩ评价十二指肠乳头区的价值。方法４２例患者做了低张力ＭＲＩ、磁共振胰胆管成像（ＭＲＣＰ）及十二指肠内窥镜对照检查。结果４２例患者中，ＭＲＩ清楚显示３５例十二指肠乳头，占全部病例的８３％。ＭＲＩ显示十二指肠乳头正常者１６例，炎性水肿１２例，早期壶腹癌７例。ＭＲＩ显示十二指肠乳头与内窥镜近似，显示壶腹癌优于内窥镜。结论低张力ＭＲＩ结合ＭＲＣＰ可作为十二指肠乳头区全面、精细的无创检查法。

Objective To study the value of MRI in evaluating the duodenal papillary region. Methods 42 patients were studied with MRI, MRCP and endoscopy. Results Of 42 cases 35(83%) duodenal papillae were demonstrated clearly by MRI. Normal papilla was seen in 16 cases, inflammatory edema in 12 cases and early carcinoma of Vater's ampulla in 7 cases. The ability of MRI in depicting duodenal papilla was similar to endoscopy, and the MRI was superior to endoscopy in evaluating the carcinoma of the ampulla. Conclusions The hypotonic MRI combined with MRCP may be taken as a non invasive and detailed method in evaluating the duodenal papillary region.
