Features and findings of treadmill exercise Cardiac MRI studies in coronary artery disease

Study	Patient population	n.	Mean Age (years)	Treadmill location	Findings
Rerkpattanapipat (2003) [33]	Patients referred for coronary angiography	27	62 ± 11	Outside scanner room	Detected coronary artery stenosis > 70% on coronary angiography with sensitivity and specificity of 79% & 85%.
Raman (2010) [31]	Patients referred for SPECT	43	54 ± 12	MR scanner room corner	Exercise stress CMR is feasible with cine wall motion and perfusion assessment and has moderate agreement with SPECT (K = 0.58)
Sukpraphrute (2015) [43]	Patients with known or suspected CAD	115	59 ± 13	Outside scanner room	Treadmill Ex-CMR RWMA assessment identified those at risk of future adverse events (myocardial infarction, death, unstable angina prompting admission) 47% with RWMA vs 17% without
Raman (EXACT trial) (2016) [45]	Patients referred for SPECT	94	59 ± 13	Scanner adjacent	Treadmill stress CMR demonstrated a stronger correlation with coronary angiography and superior specificity, sensitivity, positive and negative predictive values for > 70% stenosis at angiography than treadmill SPECT
