摘要
目的:研究磁共振成像(MRI)和磁共振胰胆管成像(magnetic resonance cholangiopancreatography,MRCP)在恶性胰胆管梗阻性疾病中的应用价值。方法:使用先进的Siemens Avanto 1.5T磁共振扫描仪,对252例可疑胰胆管梗阻性疾病及正常人行MRI和MRCP检查,原始图像作三维重建,分析图像资料并作出诊断。结果:MRCP清晰显示胰胆管的解剖结构,对胰胆管梗阻程度和梗阻部位判定的准确率达100%,恶性胰胆管梗阻端表现为突然截断、锥状或鼠尾状狭窄,结合MRI能够明确肿瘤大小和范围。MRI和MRCP诊断恶性梗阻的敏感性95%、特异性98%、准确率96%。结论:MRI和MR-CP作为无创伤性检查,准确率高,胰胆管的解剖结构显示清晰,可作为胰胆管疾病常规的检查方法,且可作为肿瘤可切除性评估标准之一。
Objective：To study the application value of MRI and MRCP in the diagnosis of pancreaticobiliary duct malignant obstructive diseases.Methods： With a advanced Siemens 1.5T magnetic instrument, MRCP was performed in 252 cases,iueluding suspicions pancreaticobiliary duct malignant obstructive diseases and normal group.Raw data was made for three-dimensional reconstuction.The findings of MRCP was analyzed and made diagnosis. Results： MRCP can exhibit the anatomic structure well of pancreaticobiliary duct. The accuracy of MRCP in determination the degree and location of pancreaticohiliary duct obstructive was 100% .The obstructive end of pancreaticobiliary duct demonstrated suddenly block,awl-like or mouse taft-like narrow. MRI and MRCP can define the tumor margin and extent.Tha sensitivity ,specificity and accuracy of MRCP were 95% ,98% ,96% respectively in diagnosis malignant obstructive diseases. Conclusion： Without traumatic examination, MRI and MRCP have high accuracy, pancresticobiliary duct anaomic structure demonstrate well. It can be as a common examination means in the diagnosis pancreaticobiliary obstructive diseases and one of standards of a preoperative assessment for the respectability.
