Abstract: Objective To explore the value of enhanced T2 star weighted angiography(ESWAN)in the treatment of uterine fibroids with high intensity focus ultrasound(HIFU) by analyzing the changes of ESWAN. Methods Uterine fibroids were detected through pelvic conventional MRI and ESWAN 1 day before and after HIFU operation. Different indexes of ESWAN were measured ,and differences were compared with the paired t-test. Results The preoperative and postoperative values of magnitude were 1624.59 ± 53.07 and 1750.13 ± 39.81, phase values were 0.0012 ± 0.0081 Hz and 0.0025 ± 0.1063 Hz,R2*value were 27.69 ± 1.27 Hz and 24.19 ± 1.20 Hz,and T2*values were 34.66 ± 2.07 ms and 36.46 ± 2.14 ms. After HIFU operation,magnitude value,phase value and T2*value were higher(P=0.04,P=0.91 and P=0.45),and R2*value was lower(P=0.019). Conclusions ESWAN can provide more information about histopathologic changes of uterine fibroids after HIFU.
