Background: Several investigators advocated that MRCP is useful in hilar cholangioscarcinoma for not only evaluation of tumor progression but also decision of strategy of biliary drainage. Recently the respiratory navigator-triggered with a prospective acquisition correction (PACE) technique for MRCP (3D-PACE-MRCP) have been developed.The aim of this preliminary study was to evaluate the ability of a 3D-PACE-MRCP to depict the biliary tract and decide the strategy of drainage for hilar cholangiocarcinomas compared to cholangiography and surgical resected specimens.Patients and Methods: Eleven potential operation of hilar cholangiocarcinomas were retrospectively evaluated with preoperative 3D-PACE-MRCP before drainage. 3D-PACE-MRCP was performed with 1.5-T magnetic field using T2-weighted PACE TSE sequence. All preoperative drainages were performed by using endoscopic nasobiliary drainages if needed. The findings of 3D-PACE-MRCP were evaluated compared to cholangiography using contrast medium and surgical resected specimens.Results: 3D-PACE-MRCP could provide very high quality imaging in 68% (7/11).The remaining 4 cases shows fair quality imaging compared to standard MRCP because disturbance of the respiration in elderly and excessive intestinal peristalsis. In seven cases showing high quality imaging, MR-cholangiographic findings were similar to direct cholangiographic findings and subsequently matched the histopathological findings. Conclusion: Although further development of MRCP is mandatory for the stable depiction, pre-operative PACE-MRCP seems to be useful for not only evaluation of tumor progression but also the strategy of pre-operative drainage for hilar cholangiocarcinomas. |
