|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|
Methods and materials
We performed a retrospective analysis of the radiation dose received by patients in two consecutive head CT scans.
We selected those patients who had a head CT scan in the new model and had another one performed in a different CT scanner. We wrote down the doses (DLP) from each exam registered in our PACS.
There were 30 patients registered (18 males and 12 females between 20 and 94 years old).
The presenting complaints were: cranioencephalic trauma, syncope, focal neurologic deficit, cephalea, postoperative follow-up, ictus follow-up, and subarachnoid hemorrhage follow-up.
For statistical analysis, we compared the doses with paired sample t-test, considering a significance level of 0.05.
