Table 1.

Signal behavior according to different kinds of myocardial diseases.

	DISEASE	T1	T2	LGE
EDEMA	Aborted MI, Tako-Tsubo	Increased	Increased	None
	Acute MI, or myocarditis	Increased	Increased	Present
FIBROSIS	Focal (replacement) or diffuse (interstitial)	Increased	Normal	Detectable if focal

Note: T1 is increased in several categories of cardiac lesions, which may not be discriminated unless T2 and LGE imaging are used as complementary tools (similarly with histology, which relies on various stains to characterize tissue pathology).
