Abstract:
Objective To study the clinical value of DTI in the evaluation of high intensity focused ultra-sound (HIFU) for treating uterine fibroids by analyzing the characteristics of DTI before and after surgery. Methods DTI was performed before and after HIFU. The study included 25 patients with 30 uterine fibroids. All data were processed using GE AW4.5 Workstation. ADC,FA,VRA and T2-weighted trace of uterine fibroids before and after HIFU were recorded and analyzed. Results After HIFU,no enhancement was observed in uterine fibroids on DCE-MRI. The signal of uterine fibroids on FA,VRA map was lower after HIFU. No statistical differences were found between ADC and T2-weighted trace before and after the surgery(P>0.05). FA and VRA of uterine fibroids after HIFU were lower than those before the surgery(P<0.05). Conclusion FA and VRA can reflect micro differ-ence of uterine fibroids before and after HIFU ,which is useful for assessing the curative effect after HIFU.
