Abstract:
Objective To explore the predictive value of the nomogram model based on multimodal MRI signs for adverse pregnancy outcomes in placenta accreta spectrum disorders(PAS).Methods The clinical and MRI data of 60 patients with PAS diagnosed by surgery and/or pathology were collected.Multivariate logistic regression was used to analyze the independent risk factors of adverse pregnancy outcomes in PAS.According to the results of multivariate logistic regression analysis,the nomogram prediction model of adverse pregnancy outcomes in PAS was constructed.Results Placenta/uterine protrusion[odds ratio(OR)=6.717,P=0.015],abnormal blood vessels in the placenta(OR=7.929,P=0.009),and diffusion weighted imaging(DWI)placental spike/nodular protrusion into the muscular layer(OR=12.134,P=0.003)were independent risk factors for adverse pregnancy outcomes in PAS.Based on the results,a nomogram prediction model was constructed.The area under the curve(AUC)of the model for predicting adverse pregnancy outcomes of PAS was 0.907,with a sensitivity of 0.906 and a specificity of 0.821.Conclusion The nomogram model constructed based on multimodal MRI signs has certain value in predicting adverse pregnancy outcomes of PAS.
