Abstract:
Objective To explore the diagnostic value of ESWAN in uterine fibroids by analyzing the ESWAN signal of uterine fibroid. Methods Conventional MRI and ESWAN were carried out in thirty-seven patients with uterine fibroids.The differences of ESWAN indexes between uterine fibroids and myometrium were analyzed by paired t-test.The value of ESWAN on diagnosing uterine fibroids was analyzed by receiver operating characteristic curve(ROC curve).Results The magnitude value,phase value,R2* value and T2*value of uterine fibroids were 1 661.69 ± 45.24,(0.006 7 ± 0.007 7)Hz,(26.69 ± 1.04)Hz and(34.68 ± 1.73)ms,respectively.The magnitude value,phase value,R2* value and T2* value of myometrium were 1 790.95 ± 49.04,(0.013 1 ± 0.011 8)Hz,(22.35 ± 0.84)Hz and(42.53 ± 2.16)ms.The magnitude value,phase value and T2* value of uterine fibroids were lower than those of myometrium (P=0.008,P=0.659 and P=0.002).While the R2* value of of uterine fibroids was higher than that of myometrium(P=0.001). The area under curve(AUC)of magnitude value,phase value,R2* value and T2* value were 0.604,0.553,0.666 and 0.662.Conclusion ESWAN can show the differences between uterine fibroids and myometrium ，while the ability to independently diagnose uterine fibroids was modest.
