MR imaging of intrahepatic cholangiocarcinoma: Use of ferumoxides for lesion localization and extension

Objective. The purpose of this study was to evaluate the use of ferumoxides in the visualization and localization of intrahepatic cholangiocarcinoma. Conclusion. The contrast-to-noise ratio of cholangiocarcinoma compared with that of the adjacent liver significantly (p < 0.03) improves after ferumoxides administration. Ferumoxides-enhanced MR imaging is a useful technique for the visualization and localization of intrahepatic cholangiocarcinoma.
