Contrast-enhanced MRA has been clinically accepted at our institution as a useful alternative to CTA for the diagnosis of pulmonary embolism, particularly in young patients where radiation dose reduction is a high priority. This increasing utilization has led to the need to understand and mitigate artifacts that are unique to MRA, increasing the diagnostic accuracy of these scans. Based upon our experience interpreting approximately 200 clinical cases, we have identified and provided potential solutions to two common artifacts that are unique to MRA.
