Figure 2. MOLLI results in the calf muscle (n = 6): A) T₁ errors obtained at 30°, 60° and 90° readout flip angle for conventional MOLLI fitting (Eq.1) and MOLLI fitting with inversion correction (Eq.2); B) Relative fitting residuals for the three parameter fit used in Eqs.1 and 2.

Note the increasing residuals with the three parameter fitting (used by Eqs.1 and 2) at higher flip angles; C) Measured signal and curves fit with the 3-parameter MOLLI fit in the calf muscle of one volunteer at 30°, 60° and 90°. Notice the increasing discrepancy between the fit and measured data at higher flip angle, confirmed by the increase in fitting residual in (B).
