Figure 3. Selection of optimal TI. One short-axis slice at mid-ventricle level is repeatedly obtained using different inversion times varying from 100-310msec., at short TI times (100-160msec.) non-viable infarcted myocardium (arrows) is mostly dark. Optimal nulling is visually selected at 250 msec. [4]
