A single breath-hold 3D method was developed for
simultaneous quantification of the T1 and T2 relaxation
time over the complete myocardial volume. T1 and T2 maps
of 13 slices were acquired in 15 heart-beats. The method
was based on a 3D cardiac triggered, interleaved
Look-Locker sequence, combined with T2 prep pulses. The
measured T1 and T2 values correlated well with T1 and T2
measurements using other methods such as inversion
recovery and multi-echo CPMG.
