From: Diffuse myocardial fibrosis using native T1 mapping in children with repaired Tetralogy of Fallot: correlation with surgical factors and exercise capacity

Figure 1

(A) T1 mapping contours and (B) derived exponential time curves plotting the native T1 times on the X-axis and signal intensity (SI) on the Y-axis in a patient post-TOF repair. The curve is 1 of 8 mid-ventricular images acquired at varying inversion times that collectively make up the MOLLI sequence. Regions of interest are drawn within the left ventricular myocardium (red and green), interventriculal septum (orange), blood pool (light blue) and the native T1 times are calculated using a curve-fitting algorithm.
