A Journal of the American College of Radiology January 2012 edition summarizes some of the articles to find the optimum dose for a CT-scan in children so as to lessen the effects of radiation.
One of the most important thing is to reduce the radiation dose from CT-scans. Another thing that can be done is to replace it with another scanning tool with ionizing radiation are low or absent such as radiography, ultrasound and MRI can provide similar diagnostic information for some clinical conditions.
"When there are no clinical indications, avoiding CT is a good strategy. But there are some steps that can be done to optimize the dose received by the children,"
Researchers from Massachusetts General Hospital, Harvard Medical School in Boston, and Johns Hopkins University in Baltimore pursuing a strategy to reduce the radiation dose associated with CT-scan in children.
The reduction of radiation dose for children begins with optimizing tool CT-scan according to body size (weight that is owned by the child), the body that will receive the radiation, clinical indications and previous imaging.
Other measures undertaken include using tubes and a lower voltage, limiting the length of the scan which only covers certain area and using a new image processing techniques.
"Children are more sensitive to radiation risks that require special attention in optimizing the proper dose of radiation to reduce the effects that might arise,".
