Figure 2. Delayed Gadolinium Enhancement Scheme: (a) A 180° pulse inverts the magnetization which then recovers. If the correct TI is chosen (b) while the segmented GRE sequence is played out, the signal from normal myocardium should be zero (dark) while signal within the infarcted tissue is hyperintense, as shown by the arrows in (b) [3]
