title: MRI of placental adhesive disorder.
abstract: Placental adhesive disorder (PAD) is a serious pregnancy complication that occurs when the chorionic villi invade the myometrium. Placenta praevia and prior caesarean section are the two important risk factors. PAD is classified on the basis of the depth of myometrial invasion (placenta accreta, placenta increta and placenta percreta). MRI is the preferred image modality for pre-natal diagnosis of PAD and as complementary technique when ultrasonography is inconclusive. Imaging findings that are helpful for the diagnosis include dark intraplacental bands, direct invasion of adjacent structures by placental tissue, interruption of normal trilayered myometrium and uterine bulging. Clinicians should be aware of imaging features of PAD to facilitate optimal patient management.
