Coronary computed tomography angiography shows absence of flow limiting stenosis in both left (1a) and right (1b) coronary circulation. A tri-dimensional data set was reformatted using the maximum intensity projection technique. In Figure 1a, the image was taken along the anterior interventricular plane, allowing fine analysis of the left main as well as the left anterior descending coronary artery. A maximum intensity projection view also allows partial assessment of the origin of the right coronary artery and the first diagonal branch. Figure 1b: an image acquired along the right atrio-ventricular groove; the maximum intensity projection image clearly depicts the right circumflex artery up to the inferior portion.

The MSCT angiographic analysis showed no coronary lesions (Figure 1), but the presence of a hypodense area involving more than 50% of the myocardial wall of the left ventricular inferior basal portion (Figure 2).
Multiplanar reformatted images generated along the conventional short cardiac axis, showing focal areas of myocardial wall thinning associated with hypodensity (arrows), suggestive for non-recent myocardial wall infarction.
