It is common MRI knowledge that iron causes rapid MR signal dephasing and artifacts. Meanwhile, many people take iron nutritional supplements for low iron status. We describe here how ingestion of a standard "over the counter" iron supplement, too soon before an MRI scan, can result in artifacts. Based on steady state imaging results and analytical measurement using a volume magnetic susceptibility balance our results demonstrate that patients should not ingest iron containing vitamin supplements prior to an abdominal MRI scan.
