Dynamic T1-weighted ferumoxides enhanced MRI for imaging liver hemangiomas: preliminary observations

Abdom Imaging. 2001 Mar-Apr;26(2):166-70. doi: 10.1007/s002610000123.

Abstract

The T1-based signal-enhancing effects of ferumoxides was studied in five liver hemangiomas on short echo-time gradient-recalled echo dynamic magnetic resonance imaging to assess the utility of this technique to image perfusion patterns in liver hemangiomas. We observed peripheral nodular enhancement with centripetal fill in all hemangiomas. Our results suggest that this imaging technique, after rapid injection of ferumoxides, can be used for lesion characterization.
