Four weeks after giving birth to twins, Tokoya Proctor cradled a three-dimensional model of her sons in her hands. Made of plastic from an MRI scan taken when Proctor was 16 weeks pregnant, it captured an exact likeness of the fetuses drowsing in her womb. Her twins were hugging, conjoined along the chest and abdomen. They shared a liver. One twin's heart poked into his brother's chest, wrapped in a common membrane with the second heart. "It was amazing," she says. "It was a work of art."
For Proctor's medical team, it was much more: a guide to the high-risk separation surgery ahead.
