You’ve heard the term CT Scan? CT scan is a procedure that is used to get an overview of the different angles of bone from the skull and brain. CT scans can be used to assess almost every organ in the body, even in foreign countries have been used as a screening tool replaces X-ray and ultrasound.
But apparently scan or CT scan performed repeatedly is very dangerous for children. Over time will increase the risk of brain cancer or leukemia than tripled, according to the findings of research team of scientists led by the University of Newcastle. Research carried out by studying the medical records almost 180 thousand young patients.
But in a research report published in The Lancet, the authors emphasize that the benefits of scanning usually outweigh the risks. They said the research underscores the fact that scanning should only be performed if necessary and that ways of reducing radiation should be sought.
During scanning, X-ray tube rotates around the patient’s body to produce a detailed picture of the internal organs and other body parts.
In the long-term study was first conducted, the researchers looked at the records of patients younger than 21 years who had to do a scan in various UK hospitals between 1985 and 2002. Since the radiation-related cancer takes time to form, they examined data of cancer cases and deaths by 2009.
Brain cancer and leukemia is a rare disease. Research estimates that the increase in risk translates into one additional case of leukemia and a brain tumor among 10,000 scanning head in children under the age of 10 years.
Dr Mark Pearce, an epidemiologist at the University of Newcastle, who led the research, said, “We found a significantly increased risk of leukemia and brain tumors, following scanning in childhood and adolescence.
“The benefits outweigh the risks scanning directly in many ways. Dose scanning decreases dramatically over time, but we must do more to reduce them. It should be a priority for the clinical community.”
Scanning is useful for children because of anesthesia and anesthesia is not recommended. Type of inspection is often ordered after a serious accident, to see the injuries, and the possibility of lung disease.
A Journal of the American College of Radiology January 2012 issue also summarizes some of the articles to find the optimum dose for a CT scan in children that can reduce the effects of radiation.
One of the most important is to reduce the radiation dose from CT scans. Another thing that can be done is to replace it with other scanning tools with ionizing radiation such as low or no radiography, ultrasound and MRI can provide the same diagnostic information for some clinical conditions.
