(a) Bullseye plot indicating representative segments of normal perfusion (blue) and perfusion defect (gray) in the patient with severe triple-vessel disease in Fig 5. Gd-DTPA concentration ([Gd-DTPA]) first-pass perfusion time-curves at (b) rest and (c) stress in the normal (blue circle) and defect (gray triangle) myocardium segments shown in (a) with best fit estimated plots from the NTHf (solid line) and AATH (dashed line) models. Estimated MBFs (ml/g/min) using the NTHf model at rest (stress) were 0.81 (1.56) in a normal segment and 0.99 (0.49) in a perfusion defect segment, and estimated MBFs using the AATH model at rest (stress) were 0.97 (1.30) in a normal segment and 0.93 (0.57) in a perfusion defect segment.
