|Impact of the employment of a new model of computed tomography in the radiation dose of head CT scans. Preliminary results in a series of 30 patients|
The radiation doses in the single source CT model with a high sensitivity detector varied between 560 and 760 mGy.cm (650.6 ± 61.3).
The doses of the other scanners varied between 735 and 1344 (889.3 ± 137.8) (Figure 1).
The difference between both values was statistically significant (p<0.0001).
The doses of the head CT scan in the new model were lower in all the patients (Figure 2), with a mean of 37% (between 5% and 110%) higher in the other CT scanners.
Figure 3 shows example images of one patient both head CT scans, showing lower radiation dose in the new model.
