This study investigated the feasibility of a novel compact MRI-compatible ergometer to evaluate myocardial tissue characteristics and blood flow. The results showed a significant increase in heart rate, RPP, native T1 and MBF by using this ergometer in healthy controls. Our study has shown an excellent reproducibility in measuring free-breathing native myocardial T1, MBF and MPR during exercise. The pilot testing demonstrated that the novel compact MRI-compatible ergometer was successful at inducing a cardiac stress state and can able to characterise exercise physiology at every stage allowing high quality MR imaging during the stress.
