雅思阅读:Reviving autopsy
TECHNOLOGY advances not only through new inventions, but also by the imaginative application of old ones. And one of the most ancient forms of scientific investigation, the post-mortem autopsy, may be ripe for just such a technological upgrade. According to a paper in this weeks Lancet, published by Ian Roberts of the John Radcliffe Hospital, in Oxford, it may soon be time to put away the scalpel and the retractor clamp, and to replace them with the body scanner.
The study of death is never a cheerful topic, but it has gone through a particularly gloomy patch over the past few decades. A recent tally by Americas Centres for Disease Control and Prevention showed that in 2007 only 8.5% of deaths in America were investigated by autopsy. In 1972 that figure was 19.3%. Britains coroners are more active, but perhaps not more accurate. Twenty-two percent of deaths in the United Kingdom lead to an autopsy. According to a government review, however, one in four is of miserable quality. The upshot in both cases is not just that the cause of individual deaths may be misascribed. More seriously, data about the processes of disease are lost, and those diseases are thus not as well understood as they might have been. Squeamish relatives of the deceased, too, often do not like the idea of bodies being cut up at the behest of coroners. Britains health department therefore commissioned Dr Roberts to study whether scanning dead bodies in the way that is routine for living ones would help. His conclusion is that it would.
