Radiation Dose Optimization for Contrast-Free Adult Skull CT Protocol

Among all radiological techniques, computed tomography delivers the highest radiation dose to the patient. Aiming for the radiological protection of those, this project set out to optimize the Contrast-free adult skull protocol of the Clinic Hospital Complex of the Federal University of Parana. Four different suggested protocols were submitted to quality control tests to analyze whether it was possible to reduce the dose without a significant loss in the image quality and decide, among those, which one could be implemented at the hospital. Two out of the four suggestions obtained satisfactory results.
