Segment-based analysis for the proposed 3-parameter fit with 27 echoes. The results show that the range of variation for average T₂ values across the six mid-ventricular myocardial segments is 4.2 ms. The range of variation for the B/A parameter is 0.01. The value predicted for B/A by Equation [6] for the given sequence parameters is 0.13 (subj = subject, seg = segment).
