磁共振胰胆管造影的临床应用

Clinical application of MR cholangiopancreatography

目的：评价ＭＲ胰胆管造影的临床应用价值。材料与方法：用重Ｔ２ＭＲ水成像技术做ＭＲ胰胆管造影１６３例。采用快速自旋回波（ＦＳＥ）和脂肪抑制技术，图像经三维（３Ｄ）最大信号强度投影（ＭＩＰ）后处理。结果：临床检查１６３例中，６１例为胰胆正常者；１０２例疑为胰胆疾患者，其中９６例阳性，６例阴性。此技术可清楚描画胰胆管的形态，展示各种疾病的异常改变，诊断正确性高。结论：ＭＲ胰胆管造影是安全、可靠的非侵袭性的检查方法，不用造影剂，能较好地评价胰胆系统的解剖和病理变化，提高诊断能力。

Purpose:To assess the clinical application value of MR cholangiopancreatography (MRCP). Materials and methods: In 163 cases, heavily T 2 weighted MRCP was performed with fast spin echo(FSE) and fast suppression. The resulting slices were then projected into a composite image using 3D a standard maxium intensity projection (MIP) algorithum. Results: In 163 cases 61 were normal persons, and 102 had doubt pancreatic and bile diseases. The technique depicted accurately image of pancreatic ducts, bile ducts and abnormal change of various desease. Conclusion: MRCP is a reliable noninvasive method for depicting the pancreatic bile ducts. It does not require iodinated contrast material.
