The little baby should not take CT
To one or two years of age of the young children, they do not have enough awareness of the danger of their own behavior is limited in the ability to control, and therefore often bump, the parents generally do not care about this very much. But if a child's head is bumped, adults will be more worried, and anxious parents may immediately think of going to the hospital for a CT scan for their child. The trouble is, while a CT scan may be helpful in determining a child's injury, it may have an impact on the child's future mental development.
Swedish scientists, writing in the latest issue of the British Medical Journal, suggest that radiation treatment in early childhood may impair future mental development.
Scientists at the Karolinska Institutet in Sweden conducted a study of more than 2,000 infants who had their birthmarks removed by radiation between 1930 and 1959, based on the Swedish army's medical records, and found that the boys who received the treatment were significantly worse than the children who did not receive the radiation treatment in their ability to learn and analyze logically by the age of eighteen or nineteen. In addition, only 17 percent of the treated children went on to high school, while 32 percent of the untreated children did.
The Swedish scientists' findings raise concerns about the effects of radiation treatment on young children. Although radiation is rarely used to treat birthmarks, it is still widely used in the treatment and detection of other diseases. For example, the use of CT to examine brain damage in children is a frequently used method. Swedish scientists have pointed out that the use of CT to examine young children must be used with caution.
Professor Hal, who participated in the study, said that a CT examination of the brain was subjected to a dose of radiation equivalent to the brain in the natural situation of a year to receive the total amount of radiation, and children even with mild brain damage, if you want to carry out CT scanning, but also at least two times, and therefore it is likely to have an impact on the child's intellectual development. However, as a medical testing method, CT itself still has obvious advantages, the problem now, one is how to reduce the amount of radiation during the CT examination, in order to suitable for children patients, medical equipment manufacturers need to make certain improvements in this regard, and the second is to determine what kind of children really need to carry out CT examination. According to Canadian researchers on the statistics of nine hospitals, to the hospital to receive treatment for children, doctors only 6% to 26% of the CT examination, and only 35% of these children really have brain abnormalities. Thus, determining the circumstances under which a child should have a CT exam is also an important topic
