A system and method for cardiovascular exercise stress magnetic resonance using a MRI-compatible treadmill and real-time imaging. The treadmill comprises non-ferromagnetic components so that it may be used in proximity to a MRI scanner. The treadmill is positioned adjacent to the MRI scan table. A treadmill control system is used to control the speed and grade of the treadmill to allow it to perform a wide range of exercise protocols. Patients complete an exercise protocol on the treadmill and are then moved to the MRI scan table. Images are acquired as quickly as possible post-exercise to more accurately diagnose cardiovascular disease in patients.
