Figure 3. Three MR modalities depict a 3-year-old anteroseptal myocardial infarction in a 42-year-old man in the left ventricular short-axis view. A, End-diastolic cine image. B, End-systolic cine image shows a wall motion defect (arrowheads in B and C) of the anteroseptal wall; images obtained with an electrocardiographically triggered breath-hold sequence (field of view, 240 x 320 mm²; matrix, 126 x 256; 9.9/4.8; flip angle, 30°; section thickness, 8 mm). C, T1-weighted image obtained 15 minutes after administration of gadopentetate dimeglumine depicts a corresponding subendocardial late enhancement; image obtained with an inversion-recovery gradient-echo sequence (field of view, 240 x 320 mm²; matrix, 165 x 256; 7.5/3.4; inversion time, 170 msec; flip angle, 25°; section thickness, 8 mm). D-F, Three contiguous sections from ²³Na MR imaging reveal elevated SI of a midventricular section in the septum and a small part of the anterior wall (arrowheads); image was obtained with an electrocardiographically triggered three-dimensional spoiled gradient-echo sequence (field of view, 450 x 450 mm²; matrix, 64 x 128; 21/3.1 msec; flip angle, 70°; section thickness, 16 mm).
