Fig. 9From: Dark-blood late gadolinium enhancement cardiovascular magnetic resonance for improved detection of subendocardial scar: a review of current techniquesSchematic overview of the IR-IR method, where an additional non-selective 180º inversion RF pulse is performed before the standard non-selective 180º inversion RF pulse. Note that the inversion time is split into two delay parameters (TD1 & TD2)Back to article page
