Goergen SK, et al. - Researchers evaluated the diagnostic accuracy of several criteria for the diagnosis of placental adhesion disorder (PAD) on magnetic resonance imaging (MRI), as well as to evaluate interobserver agreement and reader accuracy based on years of interpretive experience. For this analysis, blinded evaluation of the placental MRI studies of 28 randomly selected women, 18 with PADs and 10 without PADs, was undertaken by three radiologists with 10, 5, and 2 years' experience in placental MRI interpretation. The most sensitive, specific, and reproducible criterion for the diagnosis of PADs using MRI was an assessment of the placenta for dark bands. It was noted that assessment of uterine bulging and placental heterogeneity did not improve diagnostic accuracy.
