Impact of dark-blood preparation on IMH extent determined from T2*-weighted CMR in patients and animals. IMH extent in patients is underestimated by dark-blood-prepared T2*-weighted images at 1.5 T and 3 T (A, B, respectively). IMH extent in animals is underestimated by dark-blood-prepared T2*-weighted images at 1.5 T and 3 T (C, D, respectively). *denotes statistically significant difference (p < 0.05) between bright- and dark-blood images
