Direct visualization of solid cortical bone structures with MRI is gaining increased interest. “Bright-bone” techniques based on ultrashort echo time (UTE) and Zero TE (ZTE) sequences enable obtaining signals from the cortical bone and are thus desirable for visualizing cortical bone. This work demonstrated that high quality cortical bone imaging of the human skull and c-spine can be achieved on a clinical 3T scanner in a reasonable acquisition time (<6 minutes). This can potentially widen the usage of MRI for C-spine imaging.
