Gadoxetic acid enhanced hepatobiliary phase MRI is
useful for detection of hypointense liver metastases.
However, vessels and benign cavernous hemangiomas also
appear hypointense on gadoxetic acid enhanced MRI and
may be difficult to distinguish from one another. We
hypothesized that use of an intravascular contrast
agent, gadofosveset trisodium, in addition to gadoxetic
acid, may address this issue. The purpose of this work
was to demonstrate the feasibility of combined use of
these two contrast agents and to optimize MR parameters.
We concluded that combination of the two contrast agents
is feasible and worth testing in a clinical setting.
