Ultrasound and MRI have comparable Diagnostic Accuracy for Placenta Accreta Spectrum Disorders: Study
Researchers have found in a new study that Ultrasound and MRI show similar diagnostic accuracy for Placenta Accreta Spectrum (PAS) disorders. However, radiographic findings alone should not be relied upon for an independent diagnosis.
The purpose of this study is to conduct a complete analysis of the accuracy of ultrasound and MRI in detecting placenta accreta spectrum (PAS) disorders, as well as to investigate the accuracy of independent imaging findings in these diseases. Pubmed, Web of Science, Embase, The Cochrane Library, and Google Scholar databases were searched from their establishment to January 1, 2025. Included were all studies that used both ultrasonography and MRI to diagnose pregnant women with PAS disorder.
The ability of ultrasonography, MRI, and their independent features to diagnose PAS was evaluated using pooled sensitivity, specificity, diagnostic odds ratio (DOR), and receiver operating curves (ROC). Heterogeneity was calculated using Cochran Q and I2 statistics, and the sources of heterogeneity were investigated using meta-regression and subgroup analysis. Results: Following a series of rigorous assessments, the meta-analysis comprised 1989 pregnant women from 30 studies.
