2D MRCP与3D MRCP磁共振胰胆管成像技术对比分析

2D MRCP and 3D MRCP Magnetic Resonance Pancreas Bile Duct Image Formation Technology Contrast Analysis

目的:单次激发快速自旋回波(Thick slab 2DSSPSE)与3D快速自旋回波容积扫描(3D FSE)两种MRCP技术对胰胆管成像的临床诊断价值。材料与方法:对87例疑有胆胰疾病的患者分别行2D SSFSE和3D FSEMRCP技术成像,分析、对比影像学表现,并与手术、B超、CT、ERCP结果进行比较。结果:2D SSFSE和3D FSE MRCP对单一胰胆管结构的显示无明显差异(P>0.05)。但对胰胆管全貌(包括正常和病变时)的显示,2D MRCP优于3D MRCP,且有明显的差异(P<0.01)。对肝内胆管结石和胆总管结石,2DMRCP较3DMRCP显示率均高(P分别<0.01和<0.05);对其他胰胆管疾病的显示二者均无统计学意义(P>0.05)。结论:2D MRCP和3DMRCP成像均能很好地显示胰胆管结构与病变,但3DMRCP对胰胆管的全貌显示有优势,而2DMRCP对病变的细微结构的显示特别是细小结石的诊断更具优势。

Purpose：Single stimulation fast spinning echo （Thick slab 2D SSFSE） and 3D Fast spinning echo volume scanning （ # D FSE）. Two kind of MRCP technologies to pancreas bile duct image formation clinical diagnosis value. Materials and Methods： Doubts to 87 examples has courage the pancreas disease patient to distinguish line of 2D SSFSE and 3D the FSEMRCP technology image formation. ; Methods contrast phantom study performance and with the surgery, B ultra, CT, the ERCP result carries on the comparison. Results： 2D SSFS and 3D FSE MRCP to sole pancreas bile duct stnlcture demonstration not obvious difference （ 〉 0.05）. When to pancreas bile duct complete picture （including normal and pathological change） demonstration 2D MRCP superior 3D MRCP, Also has the obvious difference （P〈 0.01）. TO liver in bile duct stone and choledoch stone disply 2D MRCp high rate 3D MRCP, Does not have statistics significance to other pancreas bile duct disease demonstration the two （P 〉 0.05）. Conclusion： 2D MRCP and 3D MRCP the image formation can demonstrate the pancreas bile duct structure and the pathological change well but 3D MRCP to the pancreas bile duct complete picture demonstrated has the superiority, But 2DMRCP to pathological change slight structure demonstration specially the tiny stone diagnosis has the superiority.
