T1 values in patients – MOLLI vs. SASHA: Mean native T1 values derived from ROIs placed in remote and affected myocardium in a three chamber LAX slice (black rectangles) against the corresponding ROIs in the midventricular SAX plane (open circles) with MOLLI and SASHA on a population of patients. There was a statistically significant difference (p < 0.05) in T1 measurements between remote and diseased myocardium in both MOLLI and SASHA for both short axis and 3-chamber long axis acquisitions (MOLLI: SAX p = 0.0014, LAX p = 0.0026 – SASHA: SAX p = 0.0025, LAX p = 0.0019) However, there was no statistically significant difference (p > 0.05) between the MOLLI-based T1 measurements of diseased myocardium and the SASHA-based T1 measurements of remote myocardium for both short axis (p = 0.06) and 3-chamber long axis (p = 0.26) acquisitions.
