Comparative study of real-time elastography and transvaginal ultrasonography in diagnosis of cervical occupied lesions

Objective: To compare real-time elastography and transvaginal ultrasound in diagnosis of cervical occupied lesions.Methods: Elastography screening was performed on 109 cervical occupied lesions in 65 patients,and the findings were classified into 5 grades;transvaginal ultrasoungraphy was used to detect the tumor size,shape,state,border,internal echo,calcification and the rear echo changes;the results by the two methods were compared.Results: The sensitivity,specificity and accuracy were 85.71%,82.11% and 82.57%,respectively by transvaginal ultrasoungraphy,while they were 100.00%,63.16% and 67.89% in cross section,and 100.00%,58.95% and 64.22% in longitudina section,respectively by elastography.Statistical results showed there was significant difference for elastography and pathological diagnosis (P<0.01).Transvaginal ultrasound in conjunction with real-time elastography in longitudinal section and cross section were 85.71%,93.68%,92.66% and 85.71%,92.63%,91.74%,respectively,statistical results showed there was no significant difference for elastography and pathological diagnosis (P>0.05).The sensitivity,specifity and the accuracy of real-time elastography and transvaginal ultrasound and transvaginal ultrasound in conjunction with real-time elastography for cervical occupide lesions were statistically significant (P<0.01),there was no significant eifference between cross-sectional and longitudinal-sectional (P>0.05).Conclusions: Elastosonography may provide some useful information for diagnosis of cervical occupied lesions,but findings by transvaginal ultrasound are still indispensable for final diagnosis.
