|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|
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.
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.
