Effect of dark-blood magnetization preparation on T2*-weighted signal characteristics. Relative signal-to-noise (SNR), Relative contrast-to-noise (CNR) and coefficient of variations (COV) computed from T2*-weighted images in patients at 1.5 T (A, B, respectively) and 3 T (C, D, respectively) and animals at 1.5 T (E, F, respectively) and 3 T (G, H, respectively) in the acute and chronic phases of hemorrhagic MI are shown. All Relative SNR and Relative CNR were found to be less than 100 (p < 0.05); and *denotes that the measures being compared are statistically different (p < 0.05)
