目的:观察胰胆管病变磁共振胰胆管成像(MRcholangiopancreatography,MRCP)及常规MRI影像学表现,探讨二者可能的诊断价值。方法:对58例经手术病理或综合影像证实的胰胆管病变行MRCP三维容积采集薄层重建、MRCP二维厚层块投射扫描及常规MRI扫描,分析各类病变的MRCP及常规MRI影像学表现,探讨诊断价值,总结诊断经验。结果:58例胰胆管病变中胰胆管结石28例,慢性胰腺炎9例,胰腺癌9例,胆管癌5例,肝门区淋巴结转移2例,Ⅰ型先天性胆总管扩张1例,胆囊切除术后1例,胰腺分裂1例,肝移植术后1例,恶性胰管内乳头状黏液瘤1例。胰胆管良恶性病变MRCP三维容积采集薄层重建、MRCP二维厚层块投射扫描及常规MRI扫描影像表现各异,均有各自特征表现。结论:MRCP三维容积采集薄层重建、二维厚层块扫描结合常规MRI有利于胰胆管病变的定位、定性诊断及鉴别诊断,值得在有条件的医院推广应用。
OBJECTIVE: To observe MR cholangiopancreatography (MRCP) and routine MRI findings of pancreatic duct disease and to explore the possible diagnostic value of both. Methods: MRCP three-dimensional volume acquisition reconstruction, MRCP two-dimensional thick block projection scanning and conventional MRI scanning were performed in 58 cases of pathologically confirmed or confirmed pancreaticobiliary diseases. MRCP and MRI findings of various types of lesions were analyzed , Explore the diagnostic value, summarize the diagnosis experience. Results: Of the 58 cases of pancreaticobiliary duct disease, 28 cases had pancreaticobiliary stones, 9 cases of chronic pancreatitis, 9 cases of pancreatic cancer, 5 cases of cholangiocarcinoma, 2 cases of hepatic portal lymph node metastasis, 1 case of type Ⅰ congenital common bile duct dilatation, 1 case after operation, 1 case with pancreatic division, 1 case after liver transplantation and 1 case with malignant pancreatic papillary myxoma. The benign and malignant pancreatic lesions MRCP three-dimensional volume acquisition of thin-layer reconstruction, MRCP two-dimensional thick block projection scan and conventional MRI scan images showed different characteristics, have their own characteristics. Conclusion: MRCP three-dimensional volume acquisition of thin-layer reconstruction, two-dimensional thick-slice scanning combined with conventional MRI is conducive to the location of pancreaticobiliary lesions, qualitative diagnosis and differential diagnosis, it is worth to promote the use of the hospital.
