Computed tomography (CT) scans are commonly used in pediatric patients with head trauma and craniosynostosis to identify skull fractures and sutures, respectively. However, the ionizing radiation associated with the CT scans increases the pediatric patients’ risk for cancer. We developed a deep learning-based method, which consists of two networks focusing on skull and head separately, to generate high-resolution pseudo-CT (pCT) from a radial MR scan. A Dice coefficient of 0.90 ± 0.02 was obtained in the bone.Moreover, a pCT mean absolute error (MAE) of 87.5 ± 4.4 HU was achieved.
