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.
