Abstract :
Children are more sensitive to radiation than adults. Computerized
tomography (CT) consists of 25 % of all medical imaging. It
was estimated that more than 2% of all carcinomas in the USA are
due to CT scans. There is an ongoing focus on the reduction of
CT scan radiation dose. Awareness about risk-benefits of CT has
increased. Reduction of radiological exam is an important issue
because the accumulation effects of radiation can be hazardous. In
addition, proper protocol should be followed for diagnostic procedures
of ionization radiation and computerized tomography.
Effective radiation dose should range from 0.8 to 10.5 millisievert.
The same protocol should be followed in different hospitals as
well. Basic principles of radiation protection should be monitored.
As much as possible, both technician and radiologist must be present
during computerized tomography for children, and MRI and
ultrasound should be replaced if possible.
