MOdified Look Locker Inversion recovery (MOLLI) is a
commonly employed sequence for measuring cardiac T
1
,
but is subject to measurement error secondary to heart
rate variability and acquisition of "apparent" T
1
(T
1
*).
Saturation Method using Adaptive Recovery Times for
cardiac T
1
Mapping
(SMART
1
Map) is an emerging technique that is
able to account for variations in heart rate, in
conjunction with acquiring true T
1
. We
compared myocardial T
1
values
obtained with SMART
1
Map to those obtained
with MOLLI at 3T and found that SMART
1
Map
offered improved variability and repeatability.
Consequently, SMART
1
Map should enable
increased robustness and precision in myocardial tissue
characterization.
