Cervical Spine

Cervical spine imaging in the emergency department (ED) represents the largest portion of growth in CT use, according to a presentation at the 2016 annual meeting of the American College of Radiology.

Researchers from Georgia and Virginia undertook a study to assess the changing utilization of cervical spine imaging in the ED. Using national aggregate Medicare Physician Supplier Procedure Files, the researchers gathered data on all cervical spine radiography, CT, and MR examinations performed in the ED setting.

The results showed that use of cervical spine radiograph in the ED among Medicare patients increased 50.5% from 1994 to 2004, but then decreased by 50.2% by 2012. Cervical CT volumes increased every year, by 8864% from 1994 to 2012, and MR imaging grew by 1381%:

Number of Examinations in 1994 Number of Examinations in 2004 Number of Examinations in 2012
Cervical Spine Radiography Volumes 203,645 306,442 152,755
Cervical CT Volumes 6,360 570,121
MR Images 944 13,979









According to the researchers, CT overtook radiography as the dominant ED cervical spine imaging modality in 2007. Changes per 1,000 Medicare beneficiaries:

Change from 1994-2012
Radiography –27%
CT +8682%
MR +1351%
