Late gadolinium enhancement (LGE) allows depiction of
scar/fibrosis in patients with cardiovascular disease.
An inversion recovery based sequence is commonly used to
achieve suppression of healthy myocardium signal.
However, the blood pool and subendocardial scar
typically have similar signal, making it difficult to
distinguish subendocardial scar. In this work, we
propose a novel pulse sequence that uses an optimized
combination of an inversion pulse and a T

prep
composite pulse to simultaneously null both the healthy
myocardium and blood signals, producing a black-blood
LGE (BB-LGE) image without losing significant
scar-myocardium contrast.
