The aim of this study was to evaluate the diagnostic value of ultrasound (US) as compared with magnetic resonance imaging (MRI) in the detection of placenta accreta. Sensitivity, specificity, summary receiver operating characteristic curves and areas under the curve (AUCs) were described and calculated using Meta-Disc Statistical Software, Version 1.4 (Unit of Clinical Biostatistics, Ramon y Cajal Hospital, Madrid, Spain). In the 13 studies included, US sensitivity was 83% (95% confidence interval [CI] 77%-88%), US specificity was 95% (95% CI: 93%-96%) and the diagnostic odds ratio (DOR) was 63.41 (95% CI: 29.04-138.48). In the MRI studies, sensitivity was 82% (95% CI: 72%-90%), specificity was 88% (95% CI: 81%-94%) and the DOR was 22.95 (95% CI: 3.19-165.11). Summary receiver operating characteristic analysis indicated that the diagnostic value of US in detection of placenta accreta is not significantly different from that of MRI. Both US and MRI were highly sensitive and specific in the detection of placenta accreta to support effective diagnostic methods.
