Figure 9From: Characterization of myocardial T1-mapping bias caused by intramyocardial fat in inversion recovery and saturation recovery techniquesExample of T1 map at 3 T for normal subject. The chemical shift for fat is 420 Hz > 1/2TR resulting in an out-of-phase partial volume mixture across the entire heart despite off-resonance variation due to shim, as evidenced by bright T1 at myocardial border with epicardial fat. The profile of T1 across an anterior profile shows the elevated T1 at the boundary with fat.Back to article page
