Objective To study the clinical diagnostic value of transvaginal ultrasonic in early cervical carcinema and cervical neoplasis.Methotis The suspected patients with cervical carcinoma and cervical neoplasis were detected with transvaginal ultrasonography,liquid based cytology and cervical biopsy.The sonograms of transvaginal ultrasonic were retrospectively analyzed.Results In early cervical carcinoma and cervical neoplasis,the diagnostic sensitivity of transvaglnal ultrasonic was 90.9%and 83.3%;and the diagnostic specifity of transvaginal ultrasonic was 70.6% and 60.0%;the rate of missed diagnosis of transvaginal ultrasonic was 9.1% and 16.7%.Conclusion Transvaginal ultrasonic plays an important part in the clinical diagnosis of early cervical carcinoma.
