Morphometric measurements were obtained from cervical radiographs and radiographic and CBCT myelography. Receiver operating characteristic curves were generated to establish thresholds of measurements.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Intravertebral sagittal ratios were significantly different between CVCM and control horses. Dorsal myelographic column reduction was significantly different between compressed sites and non\u2010compressed sites. Full myelographic area, dural area, and spinal cord area were significantly smaller in the CVCM horses, and were significantly smaller at compressed sites when compared to non\u2010compressed sites. Reductions of full myelographic area and dural area and ratios of spinal cord area to full myelographic area and dural area were significantly larger at compressed sites when compared to non\u2010compressed sites. Diagnostic thresholds to consider for CVCM are full myelographic area <294\u2009mm\n 2<\/jats:sup>\n , dural area <188\u2009mm\n 2<\/jats:sup>\n , and spinal cord area <104\u2009mm\n 2<\/jats:sup>\n . Compressed sites were associated with thresholds of full myelographic area <274\u2009mm\n 2<\/jats:sup>\n , dural area <188\u2009mm\n 2<\/jats:sup>\n , or reduction of full myelographic area >9%, reduction of dural area >14%, spinal cord area: full myelographic area >36.7%, and spinal cord area: dural area >57.9%.\n <\/jats:p>\n <\/jats:sec>\n \n Main Limitations<\/jats:title>\n Small number of horses. CVCM horses were younger than control horses.<\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n CBCT myelography provides quantitative parameters that can support a diagnosis of CVCM and should be used alongside radiographic myelography.<\/jats:p>\n
