Abstract

A method for visualizing myocardial infarction with a three-dimensional (3D) breath-hold gated acquisition was examined. By using variable sampling in time, whole heart coverage with a single volume acquisition was achieved in 24 heart beats. In a study of 35 patients, in whom 3D volume acquisition was compared with a two-dimensional (2D) acquisition, all regions of myocardial infarction were correctly identified at 3D examination. The mean imaging time for 12 section locations was 8.0 minutes ± 3.0 with a 2D approach compared with 22 seconds ± 4 with a 3D approach (P < .001). Advantages were also noted for infarct contrast-to-noise ratio: 60 ± 37 for 3D versus 33 ± 20 for 2D imaging (P < .001). No significant differences (P > .05) were noted at qualitative assessment of myocardial suppression, endocardial border visualization, respiratory and cardiac motion artifacts, or confidence of transmurality of the infarct.
