Measured Myocardial Blood Flow values for rest and stress perfusion study. First pass perfusion is used in L1 model free and Fermi doconvolution and the whole data ranged is used in two compartment model. N = 16 patients underwent rest and Adenosine stress perfusion studies with local IRB approval and written consent for either FLASH (N = 8) or SSFP (N = 8) protocols. Imaging experiments were performed on a 3T clinical MRI system (MAGNETOM Skyra, Siemens). 60 heart beats (including 3 PD beats) were imaged with three short-axis slices being acquired per beat. Typical imaging parameters for FLASH were: FOV 360 × 270 mm2, 14° flip angle, 8 mm slice thickness, interleaved parallel acceleration R = 3, acquired matrix 192 × 111, single shot imaging duration of 53 ms. SSFP protocol used 50° flip angle and had single shot duration of 67 ms. The Gd dose was 0.075 mmol/kg for FLASH and 0.05 mmol/kg for SSFP administered at 2 ml/s.
