Abstract

Abstract: The diagnostic value of color Doppler ultrasound combined with magnetic resonance imaging in placenta implantation was analyzed in this study. 64 patients with placenta implants admitted to our hospital from January 2016 to June 2018 were selected as subjects. Color Doppler ultrasound 150 diagnosis, magnetic resonance imaging diagnosis, color Doppler ultrasound combined with magnetic resonance imaging diagnosis were performed. The surgical results were used as reference. The coincidence rate, sensitivity, specificity, positive predictive value, negative predictive value and Yoden index of the three diagnostic protocols were compared. Surgery results confirmed that there were 15 cases of adhesive placenta, 30 cases of implanted placenta and 19 cases of penetrating placenta in the 64 cases of placenta-implanted patients. The sequence of diagnose coincidence rate was:color Doppler ultrasound combined with magnetic resonance imaging > magnetic resonance imaging > color Doppler ultrasound, the difference was statistically significant (P<0.05). And the sequence of sensitivity, specificity, positive predictive value, negative predictive value, Yoden index of three diagnostic protocols was:color Doppler ultrasound combined with magnetic resonance imaging > magnetic Resonance imaging > color Doppler ultrasound, the difference was statistically significant (P<0.05). In conclusion, color Doppler ultrasound combined with magnetic resonance imaging is the best method in the diagnosis of placenta implantation, and it is a preferred imaging diagnosis scheme, which is worthy of popularization.

Key words: placenta implantation, color Doppler ultrasound, magnetic resonance imaging, Yoden index
