Comparison of image features and diagnostic value of color Doppler ultrasound and two-dimensional ultrasound in the diagnosis of ovarian sex cord-stromal tumors.

Clinical value of color Doppler ultrasound and two-dimensional ultrasound in the diagnosis of ovarian sex cord-stromal tumors (OSCSTs) were explored. A total of 91 patients with positive OSCSTs admitted to Sichuan Provincial Hospital for Women and Children from May 2014 to June 2018 were selected as research objects. There were 48 patients diagnosed by color Doppler ultrasound technology as the color Doppler group and 43 patients diagnosed by two-dimensional ultrasound technology as the two-dimensional ultrasound group. Results of ultrasound images in the two groups were compared, and the diagnostic value of two ultrasound techniques combined with detection of CA125 and CA199 for OSCSTs was compared. The real internal echo of color Doppler ultrasound was significantly higher than that of two-dimensional ultrasound (P<0.05). The blood flow signal of color Doppler ultrasound was significantly higher than that of two-dimensional ultrasound (P<0.05). The diagnostic sensitivity and diagnostic coincidence rate of color Doppler ultrasound for lymph node metastasis of OSCSTs were significantly higher than those of two-dimensional ultrasound (P<0.05). Color Doppler ultrasound combined with CA125 and CA199 detection has higher accuracy than two-dimensional ultrasound combination. In conclusion, both color Doppler ultrasound and two-dimensional ultrasound are used to observe OSCSTs for early diagnosis, but the sensitivity and diagnostic coincidence rate of color Doppler ultrasound for clinical diagnosis of OSCSTs are higher than those of two-dimensional ultrasound, so color Doppler ultrasound has higher diagnostic value in OSCSTs.
