We detail our first experiences using pTx to quantitatively
map T1 via a dual-flip angle approach at
7T. A human volunteer was scanned in both static/CP mode and with kT-points RF
pulses.
The reduction in inhomogeneity simplifies bias correction.
R1
maps corrected with UNICORT with (a) conventional sinc RF pulse in CP mode, and
(b) with k-T points pulse.
Histograms (brain-masked) of uncorrected and
UNICORT-corrected R1 with (a) conventional sinc RF pulse in CP mode, and (b) with
k-T points pulse.
