The woman in question is 41 years old and is experiencing her second pregnancy. She has one child from her previous pregnancy, during which she underwent a cesarean section due to the child’s pelvic positioning. Currently, she is 35 weeks pregnant and has been diagnosed with placenta previa. If an MRI were to indicate placenta accreta, we would install a balloon in the internal iliac artery prior to surgery. This is a precautionary step designed to manage potential massive hemorrhage. How is an adherent placenta accreta spectrum (PAS) using an MRI?
