Abstract:

The diagnostic quality of magnetic resonance angiography (MRA) depends on the reliable suppression of venous signal, which otherwise overlaps arterial signal. In the case presented here, the quality of non-enhanced MRA was severely contaminated by venous signal due to a therapeutic iron infusion (ferumoxytol, intravascular half-life ~15 hours) two days prior to the MRA exam. The cause of the venous contamination was that intravenously injected ferumoxytol substantially shortened the longitudinal relaxation time (T1) of the blood, so that venous presaturation no longer was effective. This case highlights the importance of considering prior iron infusion as a cause of MRA artifacts and including it in the pre-exam questionnaire.
