Small subendocardial infarctions are sometimes difficult to identify in late enhancement MRI, especially when the left ventricular cavity is bright. The aim of the study was therefore to image myocardial infarction with a multislice saturation recovery (SR) inversion recovery (IR) GRE sequence to null both, the signal of normal myocardium and blood in the ventricular cavity. A standard IR-GRE sequence in multislice technique served as reference technique. The calculation of contrast-to-noise ratios (CNR) resulted in no statistically significant differences regarding infarction/myocardium, however, CNR of infarction/left ventricular cavity was significantly higher in the SR-IR-GRE sequence. Image quality was equal.
