Role of MRI in the Diagnosis of Placenta Previa to Assess Suspected Placental Invasion

Abstract

In recent years, there has been increased interest in magnetic resonance (MR) imaging for the evaluation of PA, since it can provide information on depth of invasion and more clearly depict posterior placentas. It can be used as complementary imaging modality and problem solving method especially with equivocal ultrasound or Doppler examination and when further characterization is require.MRI may rule out or confirm a diagnosis, for example, the presence of parametrial invasion in cases of placental adherence which results in modifications of surgical techniques, allowing a reduction in historical morbidity and a significant increase in conservative surgeries Key word - MRI- Previa/Accreta
