Einerson BD, et al. - Researchers here investigated if magnetic resonance imaging provides data that may inform clinical management by changing the sonographic diagnosis of placenta accreta spectrum disorders. In more than one-third of cases, magnetic resonance imaging led to a change in diagnosis that could alter clinical management of placenta accreta spectrum disorders, however, when changed, the diagnosis was often incorrect. Considering its high cost and limited clinical value, they recommended not using magnetic resonance imaging routinely as an adjunct to ultrasound in the diagnosis of placenta accreta spectrum.
