Computed tomography (CT) is the reference method for skull imaging, but can cause cancer due to ionizing radiation. Magnetic resonance imaging (MRI) is safer, but the prolonged scan time increases the chance of motion, especially for pediatric patients. Sedation helps reduce motion significantly, but is associated with risks. A sedation-free MRI scheme that is robust to motion is therefore highly desirable. Here, we proposed such a method by making use of a radial acquisition scheme that is inherently robust to motion. The robustness was further boosted by a forward-modeled motion-corrected reconstruction. The results show the promise of the method.
