It would be extremely valuable if the exact locations of the presumed occult fractures were to be reported. At what vertebral levels? In what parts of the vertebrae? Body? Facett joints? Posterior arch? There also must be an excellent opportunity to correlate the SPECT findings with MRI since all patients also were part of an earlier reported MRI study (Kongsted A 2008).It also seems likely that a majority of these patients have undergone acute CT of the cervical spine after the trauma - another opportunity for imaging correlations
