Abstract:
ObjectiveTo investigate the clinical value of transvaginal elastography in diagnosing cervical cancers.MethodsTotally,124 patients of cervical lesions with definite pathological results were enrolled.Elastograms were collected and the strain ratios of the benign and malignant lesions were record and compared.ROC curve was used to find the best cut-off point.ResultsElastography was useful in differentiating benign and malignant lesions by different color.Values of strain ratio of different pathological lesions were statistically different ( P ＜0.01).The mean value of strain ratio was 2.71 ± 1.56 for benign lesions and 8.32 ± 4.11 for malignant ones.The best cut-off point was 4.99 basing on the ROC curve.The sensitivity and specificity were 80.7％ and 89.6％,respectively.ConclusionsReal-time transvaginal elastography was a new way in differential diagnosing cervical cancers from benign lesions of the cervix.
