Conclusion and Recommendations
The main principles for dose reduction in pediatric CT are:
1.- A rigorous justification of the exam
2.- Adequate preparation of the patient
3.- Accept image noise as long as the scan is diagnostic.
Define the appropriate target image quality.
4.- Optimise scan parameters
5.- Limit scan coverage
6.- Avoid non-justified multiple scans of the same area
7.- Make use of the iterative reconstruction techniques,
if available
8.- Pay attention to radiation dose values and compare with diagnostic reference levels (DRL).
The proper protocol depends on the specific features of the scanner; one approach is not appropriate for all CT scanner manufacturers.
CT technology is increasingly complex and ever changing.
We need support from a qualified medical physicist and the CT manufacturer to make our best with the unique aspects of the CT scanners.
