【 要旨 】 MRCPは膵胆道系を明瞭にかつ非侵襲要的に描出できる検査法である.ERCPのように検者に特別な技術を要さない.正常例でもほぼ全例で,主膵管,肝外胆管~肝内胆管二次分枝が描出可能である.MRCPではERCPと異なり狭窄・閉塞部の遠位側の情報が得られる.MRCPは膵管との交通や膵管内の粘液に関係なく膵嚢胞性病変を明瞭に描出できる.また膵頭十二指腸切除術,Billroth-II法,Roux-en-Y吻合術などの術後症例でも検査が容易である.膵胆道疾患の診断においてMRCPはERCPにほぼ匹敵する成績が得られている.

[ Summary ] Magnetic resonance cholangiopancreatography (MRCP) is a recently developed technique that noninvasively demonstrates the biliary tree and pancreatic ducts, as does ERCP, from several perspectives. The HASTE-MRCP has been reported to fully delineate the main pancreatic duct and the extrahepatic bile ducts in virtually all normal volunteers and patients with pancreatobiliary diseases. MRCP has several advantages over ERCP. MRCP is quite safe and is not operator dependent. MRCP demonstrates ducts proximal to a severe obstruction. MRCP completely depicts pancreatic cystic lesions regardless of pancreatic ductal communication or mucin. MRCP is not limited in patients with altered pancreatobiliary anatomy due to surgical treatment. MRCP can be used as a noninvasive screening method for pancreatic diseases.
