Abstract：Objective:To evaluate the value of multi-stage dynamic enhanced scanning in the diagnosis of rich cell type uterine leiomyoma(CUL)and degenerative uterine leiomyoma(DUL).Methods:All 30 patients with CUL and 60 patients with DUL received in hospital from January 2021 to December 2023 were selected,and all patients underwent multi-phase dynamic enhanced magnetic resonance scanning.Results:The parameter values of volume transport con-stant(Ktrans),model rate constant(Kep),vascular(plasma)interstitial volume fraction(Vp)and extravascular extra-cellular volume ratio(Ve)of cell-rich uterine leiomyoma were higher than those of degenerative uterine leiomyoma(P＜0.05).CUL hysteromyoma can be better observed in the diagnosis of ET model value(ET)Ktrans.When the area un-der the curve reaches 0.956,the sensitivity and specificity can reach 1.000 and 0.867 respectively.In addition,when the area under the curve of Kep is 0.868 in ET model,the sensitivity and specificity can reach 1.000 and 0.756 respective-ly.Conclusion:Ktrans,Kep,Vp and Ve have higher differentiation efficiency in differentiating DUL from CUL hystero-myoma,which is helpful for doctors to accurately judge the patient's condition.
