Efficiency of multimodal magnetic resonance imaging in diagnosis of uterine fibroids
Objective:To analyze efficiency of multimodal magnetic resonance imaging(MRI)in diagnosis of uterine fibroids.Methods:A cross-sectional study was conducted on 80 patients with suspected uterine fibroids admitted to the hospital from January 2022 to June 2023.Conventional MRI,dynamic contrast-enhanced MRI(DCE-MRI)and diffusion weighted imaging(DWI)were performed after admission.The diagnostic results of conventional MRI,DCE-MRI,DWI and multimodal MRI for uterine fibroids were statistically analyzed.Using the results of surgical pathological examination as the gold standard,The efficiency in the diagnosis of uterine fibroids and the levels of MRI parameters in the patients with different types of uterine fibroids and non-uterine fibroids were compared.Results:The surgical pathological examination showed that among the 80 patients with suspected uterine fibroids,62 cases were diagnosed as uterine fibroids,and 18 cases were diagnosed as non-uterine fibroids;conventional MRI detected 54 cases of uterine fibroids;DCE-MRI detected 58 cases of uterine fibroids;DWI detected 58 cases of uterine fibroids;multimodal MRI detected 62 cases of uterine fibroids.The accuracy of multimodal MRI in the diagnosis of uterine fibroids was higher than that of conventional MRI,DCE-MRI and DWI;the sensitivity was higher than that of conventional MRI and DCE-MRI;the positive predictive value and the negative predictive value were higher than those of conventional MRI;and the differences were statistically significant(P<0.05).The volume transfer constant(Ktrans),rate constant(Kep)and fractional plasma volume(Vp)of the patients with cellular leiomyoma were higher than those of the patients with non-uterine fibroids,common type and degenerative type,the extravascular extracellular volume fraction(Ve)was higher than that of the patients with degenerative type,the ADC value was lower than that of the patients with common type,and the differences were statistically significant(P<0.05).The Ve of the patients with degenerative type was lower than that of the patients with non-uterine fibroids and common type;the ADC values of the patients with non-uterine fibroids and degenerative type were lower than those of the patients with common type;and the differences were statistically significant(P<0.05).However,there were no significant differences in the Ktrans,Kep and Vp among the patients with non-uterine fibroids,common type and degenerative type(P>0.05).Conclusions:The efficiency of multimodal MRI in the diagnosis of uterine fibroids is higher than that of conventional MRI,DCE-MRI and DWI.
