In noncontrast FBI run-off MRA, finding the systolic and diastolic ECG triggering delay times is an important factor to influence the resulting FBI images. A simple auto-ECG algorithm using heart rate was developed to determine the systolic and diastolic triggering delay times. The result of the auto-ECG and the manual ECG-prep method gives similar image quality in all 12 volunteers. In addition, the total operator examination time for three-station run-offs was tremendously improved using the auto-ECG.
