Aims and objectives




A large number of computed tomography scans are performed in everyday clinical practice nowadays; hence this technique has become the largest source of medical radiation.


The benefits of a computed tomography scan outweigh the risks provided that the exam is indicated and that it is optimized to get a good image quality with the lowest possible dose of radiation.



Our study


Recently, our hospital incorporated a new single-source CT equipment with a high sensitivity detector


The high sensitivity detector consists of the integration of analog-digital converters with the photodiodes of the CT detectors. This implies a reduction of the electronic noise in the image acquisition, entailing the possibility of lowering the radiation dose.


Therefore, the purpose of this study was to estimate the impact of employing a new single-source CT model with a high sensitivity detector in the radiation dose produced by a head CT scan.
