In multi-parametric MRI several MR parameters are
estimated within one single scan, which reduces
acquisition time. In this work we modified a multi-echo
spin-echo sequence for simultaneous estimation of M
0
,
T
1
, and T
2
using
the Generating Functions formalism. Reducing the
refocusing angle allows longitudinal magnetization
recovery during the sequence, which is used to create a
final T
1
weighted
echo. Simulations, measurements and fitted T
2
values
are in excellent agreement; however, accuracy of fitted
T
1
values
is limited, requiring a thorough sensitivity assessment.
The robust spin echo nature and reduced SAR of this
sequence render it applicable at high field scanners.
