WebApr 12, 2024 · 4. T1 mapping with Modified Look-Locker Inversion “MOLLI” recovery. Currently, the most evaluated sequence for myocardium T1 mapping is a modified Look-Locker inversion recovery (MOLLI) sequence [13, 14]. The T1 mapping identifies a significant variation between normal and abnormal myocardium. WebBackground: In cardiac T 1 mapping, a series of T 1-weighted (T 1 w) images are collected and numerically fitted to a two or three-parameter model of the signal recovery to estimate voxel-wise T 1 values. To reduce the scan time, one can collect fewer T 1 w images, albeit at the cost of precision or/and accuracy. Recently, the feasibility of using a neural network …
