Clinical value and accuracy analysis of magnetic resonance imaging in diagnosis of adenomyosis of uterus
Objective To explore the advantages of magnetic resonance imaging(MRI)in the diagnosis of uterine adenomyosis.Methods 60 patients suspected of adenomyosis were examined by ultrasound and MRI before operation.With the results of pathological examination as the gold standard,the diagnostic efficacy of the two methods and the MRI imaging features of adenomyosis were compared.Results Of the 60 suspected patients with adenomyosis,43 cases were confirmed by operation and pathological examination,and 17 cases were negative.The diagnostic specificity,sensitivity and accuracy of MRI were higher than those of ultrasound,while the rate of missed diagnosis and misdiagnosis were lower than those of ultrasound,with statistical significance(P＜0.05).Of the 43 patients with adenomyosis,34 were pathologically diagnosed as diffuse adenomyosis.By pathological examination,9 cases were diagnosed as localized adenomyosis,of which diffuse adenomyosis showed uniform enlargement of uterus on MRI,and diffuse,uniform/uneven thickening[mean(20.32±6.38)mm]on T2WI.There was no clear boundary between the binding zone,intima and external muscle layer,which was difficult to distinguish from normal muscle layer.There were 10 cases with saccular hypersignal.In addition,MRI images of localized adenomyosis of uterus showed localized enlargement of the myometrium with irregular/quasi-circular/oval shape and unclear boundary with the peripheral myometrium.Conclusion MRI has high clinical value and accuracy in the early diagnosis of adenomyosis of uterus,which is worthy of clinical popularization and application.
