The injury to the brain caused by a blow happens when the brain is shaken, often in a car crash or a fall or a strike to the head in sports. It can be mild, but doctors may order a CT scan to look for a more serious injury. Computed X-rays provides a detailed image of the brain. But a recent study warned that more children than necessary are being exposed to radiation this way. A national team led by two doctors at the University of California, Davis, studied hospital records from thousands of children with head injuries. They found that in many cases, the risk of developing cancer from the radiation outweighed the risk of a serious brain injury. The study found that one in five children over age two had a low risk of serious injury but received CT scans anyway. The same was true of almost one in four children under age two. The researchers have developed rules to predict if a head injury is serious enough for a scan. For children under two, doctors are advised against it if there is: normal mental activity, no swelling in the back of the head, no feeling of a broken bone in the skull, and no loss of consciousness for more than five seconds. Doctors should also consider how the child was injured and whether the parents say the child is acting normally. For patients from two to 18, the guidelines are similar—except there should be no loss of consciousness, no vomiting and no severe headache.
19. What’s the new discovery about CT scan?
20. What did the national team find after studying records about children with head injuries?
21. When can a child be given a scan?
选项
A、When a child aged two has no broken bone in the skull.
B、When a child aged ten lose consciousness.
C、When a child aged one has no serious headache.
D、When a child aged nine has normal mental activity.
答案
B
解析
推理判断题。短文中提到,研究人员制定了一些准则来预测脑损伤到达什么程度才需要进行CT扫描。对于2岁至18岁的病人,只要没有失去意识、没有呕吐或者严重头疼,都不需要进行CT扫描。由此可以推断,当2岁至18岁的病人失去意识、呕吐或者严重头疼时可以进行CT扫描。
