Abstract
PURPOSE: The aim was to establish a method for performing dynamic exercise during magnetic resonance imaging (MRI) using a slowly increasing workload protocol.
METHODS: An ergometer bicycle with a step-wise, exercise protocol was used. Real-time phase-contrast MRI images of the aorta were obtained at each exercise step.
RESULTS: In total, 40 participants completed the exercise protocol to reach a mean maximum cardiac output of 13.7±3.7l/min and a heart rate of 150±16beats/min at the highest exercise level. Less than 1% of scans were discarded due to poor quality.
CONCLUSIONS: Dynamic, high intensity exercise is feasible during MRI.
