3D-printed fetus models allow surgeons to identify potential obstacles, reduce risks of surgery A state-of-the-art in-utero procedure allows surgeons to correct a birth defect on developing babies inside the womb. But operating on a mother and her unborn child at the same time can be challenging and unpredictable. To give their world-class surgeons even more information ahead of surgery, Orlando Health Winnie Palmer Hospital for Women & Babies is using MRI and ultrasound imaging along with 3D-printing technology to create a first-of-its-kind detailed model that allows surgeons to plan procedures ahead of time, identifying potential obstacles and reducing the risks of surgery.
