ABSTRACT
Objective:To explore the application value of 3.0T magnetic resonance imaging(MRI)combined with transvaginal ultrasound elastography technique in diagnosing uterine fibroids and adenomyosis.Methods:A retrospective analysis was performed on 56 patients with uterine fibroids and 41 patients with adenomyosis who admitted to Fengfeng General Hospital of North China Medical and Health Group from January 2021 to January 2022.MRI and transvaginal ultrasound elastography were respectively performed on all patients,and pathological diagnosis was taken as the"gold standard".The diagnostic results of MRI,transvaginal ultrasound elastography technique and their combination were compared,and the diagnostic situation of different examination methods were recorded.And then,the total coincidence rate was analyzed,and the sensitivity,specificity and accuracy were further calculated.Results:The totally diagnostic coincidence rate of MRI combined with transvaginal ultrasound elastography was 96.43% in detecting uterine fibroids,and that of MRI was 75.00%,and that of transvaginal ultrasonography was 80.36%.The differences of totally diagnostic coincidence rates among combined detection and single detection were significant(x2=10.500,7.049,P＜0.05).The totally diagnostic coincidence rate of MRI combined with transvaginal ultrasound elastography was 97.56% in detecting adenomyosis,which was significantly higher than that(78.05%)of MRI and that(78.05%)of transvaginal ultrasound elastography,and the differences were significant(x2=7.289,7.289,P＜0.05).The sensitivities of single MRI,single transvaginal ultrasound elastography and the combined detection of them were 71.74%,78.26% and 95.62% in detecting uterine fibroids,and the specificities of them were 90.00%,90.00% and 100.00%,and the accuracies of them were 75.00%,80.36% and 96.43%,respectively.The sensitivity and accuracy of the combined detection were significantly higher than those of single MRI detection(x2=5.029,10.500,P＜0.05),respectively.The accuracy of the combined detection was significantly higher than that of the single detection of vaginal ultrasonography(x2=7.049,P＜0.05).The sensitivities of single MRI,single transvaginal ultrasound elastography and the combined detection of them were 81.25%,78.73% and 96.88% in detecting adenomyosis,and the specificities of them were 66.67%,77.78% and 100.00%,and the accuracies of them were 78.05%,78.05% and 97.56%,respectively.The accuracy of the combined detection was significantly higher than that of single MRI detection(x2=7.289,P＜0.05),and the accuracy of the combined detection was significantly higher than that of single detection of vaginal ultrasonography(x2=7.289,P＜0.05).Conclusion:The diagnosis rate of MRI combined with transvaginal ultrasound elastography technique is higher for uterine fibroids and adenomyosis,which has better diagnostic value,and can provide reliable reference materials for clinicians in performing treatment.
