Abstract:
Objective To evaluate the diagnostic value of ultrasonography and MRI in the diagnosis of placenta accrete.Methods First,the relevant literatures about placenta accrete were retrieved at home and abroad,then the data were extracted and Meta-analysis was performed.The combined sensitivity and specificity of ultrasound and MRI and AUC were obtained.Results The combined sensitivity of ultrasonography was 0.80,specificity was 0.88,AUC was 0.88;combined sensitivity of MRI was 0.86,specificity was 0.90,AUC was 0.93.Conclusion Ultrasound and MRI are very valuable in the diagnosis of placenta accrete.However,MRI is a useful complement of ultrasound,and the diagnostic value is slightly better than that of ultrasound.The diagnostic value will be higher when they combined together.
