Dark-blood late gadolinium enhancement cardiovascular magnetic resonance for improved detection of subendocardial scar: a review of current techniques

Table 2 Black-blood versus gray-blood LGE with conventional bright-blood LGE as a reference

	Black-blood LGE	Gray-blood LGE
Scar-to-blood contrast	↑ ↑	↑
Scar-to-myocardium contrast	○ / ↓^a	○
Myocardium-to-blood contrast	↓ ↓ / ↓^a	↓
Assessment of scar transmurality	○ / ↑^a	↑
MI size quantification	↑ ↑ / ↑^a	↑
MVO detection	○^b	○^b
LV thrombus detection	↓ ↓	○

Indicated values are relative to conventional (bright-blood) LGE with normal myocardium nulling: ↑ = increased, ↓ = decreased, ○ = maintained
^aFirst value indicative for black-blood methods that simultaneously null both blood pool and normal myocardium (both appear black), second value indicative for black-blood methods with a dark-gray appearance of the normal myocardium
^bEqual detection but might improve differentiation with thrombus
LGE = late gadolinium enhancement, LV = left-ventricular, MI = myocardial infarction, MVO = microvascular obstruction
