It has been reported
that T1 in skeletal muscles is proportional to the percentage of
typeⅠfibers which would be a determinant for athletic performance. However,
the precision of the measured T1 values is unclear due to various
pulse sequences used for the measurement. In this study, we evaluated the reliability of T1 measured
by pulse sequences with inversion recovery technique that is believed to be
most accurate in T1 measurement. A value of goodness of fitting was
employed for the quantitative evaluation of the obtained data. The influence of
SNR on the T1 measurement was also examined.
