In recent study, f map of intravoxel incoherent
motion(IVIM) model which indicates the blood volume
ratio was applied to measure the treated region of
uterine fibroid in magnetic resonance guided high
focused ultrasound treatment. In this study, it was
reported that the T2 value increased in the treated
region affected the asymptotic fitting for IVIM. The
mismatch of the perfusion information and thermal dose
for the uterine fibroid after HIFU therapy can be
eliminated by T2 correction.
