Elevated myocardial native T1 
Increased duration of myocardial T1 time without gadolinium contrast. T1 mapping consists of quantifying the T1 relaxation time of a tissue by using analytical expressions of image-based signal intensities. A fundamental principle of MR imaging is that the signal intensity of pixels is based on the relaxation of hydrogen nuclei protons in a static magnetic field. The T1 relaxation times between two tissues vary substantially. Edema, fat infiltration, and fibrosis also cause differences in T1 relaxivity.
