A
Modified Look-Locker with saturation recovery sequence was evaluated on nine
patients using different data sampling schemes. The proposed sequence enables
flexibility in sampling schemes and an approach comparing a typical 16
heartbeat data acquisition with 8 samples of the signal recovery is compared
to an approach that samples only 4 points during the signal recovery in 8
heartbeats. T1 values in normal myocardial tissue pre- and post-contrast, and
infarcted myocardial tissue post-contrast, are measured and quantified on
patients and volunteers. Accurate T1 estimates can be obtained using reduced
data sampling.
