Solid-state MRI via 3D UTE or ZTE methods has potential for bone-selective imaging as a radiation-free alternative to computed tomography, particularly for children with craniofacial abnormalities. However, relatively long scan times make the technique vulnerable to artifacts from involuntary subject movements, thereby impairing image quality. Here, we developed a self-navigated, rapid 3D UTE technique by combining a retrospective motion detection and correction approach with sparsity-constrained image reconstruction. Results from in vivo studies demonstrate the proposed method's feasibility in achieving motion-corrected whole-skull images at 1 mm isotropic resolution in 2.1 minutes scan time.
