| Measure | Time frame |
|---|---|
| T1 mapping was conducted using modified look-locker inversion recovery (MOLLI) sequences to measure the T1 relaxation time values of the myocardium and LV (1). Regions of Interest were drawn on the short axis images of areas of the myocardium without lesion involvement, at the LV septal/inferior walls, and in the LV cavity. An inversion scout sequence was also acquired seven min after mGBCA administration. Null points were defined as the inversion times (TI) that showed the lowest intensities of the myocardium and LV in each patient. The biological parameters of ejection fraction, estimated glomerular filtration rate, hematocrit, and heart rate were also compared across the three groups. | — |
