USC researchers have developed a potential solution: flexible MRI sensors that can be customized to individual patients and 3D-printed in less than 10 minutes for about $30. That makes fit especially important for small patients. “But if you can tailor the lens, in this case the MRI coil, to the individual patient, you can capture a much better image.” That required rethinking both the material and the way MRI coils are manufactured. “This project wouldn’t have happened without access to the MRI and conversations with cardiologists, radiologists and imaging scientists.
