Abstract:
Objective To evaluate the value of superb micro-vascular imaging( SMI) in evaluating the efficacy of uterine fibroids treated with high intensity focused ultrasound( HIFU) . Methods Forty patients with single fibroid were selected before and after HIFU treatment ,color Doppler flow imaging(CDFI) ,SMI and contrast-enhanced ultrasound ( CEUS ) pattern were used to detect the lesions . CEUS was used as standard . The correlation of different blood flow levels in the fibroids with SMI and the efficacy of HIFU were evaluated . Results Before HIFU treatment ,the blood flow signals of different degrees were found in the uterine fibroids . SMI showed that 4 fibroids( 10 .0％ ) were in the first degree ,21 fibroids( 52 .5％ ) were in the second degree and 15 fibroids ( 37 .5％ ) were in the third degree . CEUS showed that 8 fibroids ( 20 .0％ ) were hypo-enhanced ,19 fibroids( 47 .5％ ) were iso-enhanced and 13 fobroids(32 .5％ ) were hyper-enhanced . The correlation analysis showed that there was close relationship between the results of SMI and CEUS( Kappa = 0 .754 , P = 0 .00) . After HIFU treatment ,SMI and CEUS had no statistical difference in evaluating the efficacy of HIFU( P > 0 .05) . The ratio of non-perfused volume and the ratio of the volume reduction at 6 months after HIFU in the third degree of SMI were lower than those in the first and second degrees( P < 0 .05) . Conclusions There are some relationships between SMI and CEUS in evaluating the blood flow signal of uterine fibroids . SMI can prompt therapeutic efficacy of uterine fibroids ablated by HIFU and provide some clinical reference values .
