To simultaneously acquire information on R2, MBF, and
restricted water diffusion in lower-leg, we devised a
method using SE-diffusion-EPI imaging with different
echo times, and compared these values before and after
the exercise. R2, ADCr, ADCP, and Fp of the tibialis
anterior (TA) of the lower-leg muscle after the exercise
were significantly higher than those before the
exercise. On the other hand, there was no significant
correlation between R2, ADCr, ADCP, and Fp of the TA.
Our method makes it possible to simultaneously obtain
R2, MBF, and restricted water diffusion in lower-leg,
and increase amount of the muscle functional
information.
