摘要：

Dynamic magnetic resonance (MR) imaging of the left ventricle was performed in 13 patients with acute myocardial infarction and in 11 healthy volunteers. Visual assessment of cine MR video loops correctly located the infarction of 12 of 13 patients. Quantitative analysis of absolute and relative wall thickening, area ejection fraction, and radial shortening fraction accurately distinguished hearts with and without infarction (p < .001). This distinction could also be made using the number of segments with decreased and the number of segments with decreased + increased wall motion (p < .001). Localization of the infarction by quantitative MR methods was limited, probably due to relative low temporal resolution. Combined evaluation of qualitative and quantitative MR imaging data provides useful information on wall motion dynamics after acute myocardial infarction.
