Abstract: To explore the application and clinical value of transvaginal color Doppler ultrasound in the clinical diagnosis of endometrial lesions. The patients with endometrial diseases were examined by abdominal Doppler ultrasound and transvaginal color Doppler ultrasound, and the diagnostic coincidence rate of the two ultrasound results and pathological results was compared. The results showed that the diagnostic coincidence rate of endometrial cancer, endometrial polyp, endometrial hyperplasia, and submucosal myoma of uterus was significantly different in different examination methods (P<0.05).The diagnostic coincidence rate of transvaginal color Doppler ultrasound was significantly higher than that of abdominal Doppler ultrasound. Among the patients with benign lesions, 21.78% presented blood flow signals, and the patients with malignant lesions, 100% presented blood flow signals (P<0.05). There is little difference between the diagnostic accuracy of transvaginal color Doppler ultrasound and pathological examination in endometrial lesions,and the diagnostic accuracy is higher, which can be 862 used as a detection method for endometrial lesions in married women.

Key words: endometrial lesions, transvaginal color Doppler ultrasound, abdominal Doppler ultrasound, clinical value
