Abstract 【Objective】To explore the value of intravoxel incoherent motion diffusion weighted imaging (IVIM-DWI) in evaluating the efficacy of high intensity focused ultrasound (HIFU) in the treatment of uterine leiomyoma. 【Methods】A total of 76 patients with uterine leiomyoma treated in Baoji Hospital Affiliated to Xi'an Medical College from January 2018 to March 2019 were selected and treated with HIFU. The IVIM-DWI was performed before and after treatment and its predictive value for HIFU treatment was evaluated. 【Results】After treatment, the true diffusion coefficient (D) value higher than that before treatment ( P <0.05), while the correlation diffusion coefficient (D^*) value and perfusion fraction (F value) were significantly lower than those before treatment ( P <0.05). The changes of D^* and F values in the group with leiomyoma ablation rate > 50% were significantly higher than those in the group with leiomyoma ablation rate ≤50% ( P <0.05). The area under ROC curve for predicting ablation rate of leiomyoma > 50% by the changes of D^* value and F value was 0.681 and 0.901,respectively. Meanwhile, the cut-off values were 16.71×10^-3 mm²/s and 15.70 mm²/s, the sensitivity was 58.60% and 82.80%, and the specificity was 77.80% and 88.90%.【Conclusion】IVIM-DWI parameters have certain application value in predicting the efficacy of HIFU in the treatment of uterine leiomyoma, which is worthy of clinical use.
