“…The patients were then evaluated using a single-detector helical CT protocol (Somotom Plus 4; Siemens, Iselin, NJ) for the entire cervical spine (one 24-sec acquisition to T1, 3-mm slice thickness, pitch of 1.5:1, 120 kVp, 240 mA) after one portable in-collar lateral radiograph (75 kVp, 40 mAs, 72-inch [183 cm] focal-film distance) had been obtained. Completion radiographs were not obtained [19]. The attenuation of the collar was determined to be negligible (<2%) via direct X-ray beam transmission measurements.…”

The correlation between the ionization chamber estimates and the thermoluminescent dosimeter measurements supports the use of ionization chamber estimates in future research. Although helical CT of the entire cervical spine is cost-effective in patients at high risk for fracture, the greater than 14-fold increase in the radiation dose to the thyroid emphasizes the importance of clinical stratification to identify patients at high risk for fracture and the judicious use of CT in patients with suspected cervical spine injury.
