Figure 4

Example of the fit for the short acquisition and using 27 T2prep echoes, for the same vial in Figure 3, where the signal in the region of interest (ROI) is averaged prior to fitting. With the short acquisition, the 2-parameter overestimates the T2 value, as apparent in the under-estimation of the non-zero signal for “T2prep = ∞.” The proposed 3-parameter fit with SAT image fits this signal value well for both 3 and 27 T2prep echoes. With 27 echoes, the 3-parameter fit without SAT image matches the behavior of the proposed 3-parameter fit with SAT image, while the 2-parameter fit still overestimates the T2 values.
