US doctors from Duke University warn that relying on standard X-rays alone to give a clean bill of health could lead to wrong diagnoses and lawsuits. When they re-checked the X-ray results of 92 patients using a more detailed scanner, called MRI, they found 35 fractures that had been missed. The findings are published in the American Journal of Roentgenology. Dr. Charles Spritzer, who led the research, said: "The diagnosis of traumatic fracture most often begins and ends with X-rays of the hip, pelvis, or both. In some cases though, the exclusion of a traumatic fracture is difficult."
Questions 1 and 2 will be based on the following news item.
1. According to the research findings, what can we learn?
2. When doctors re-checked the X-ray results of 92 patients with MRI, how many fractures did they find that had been missed?
选项 A、People cannot always rely on X-ray to diagnose disease.
B、X-ray is always helpful in diagnosing disease.
C、X-ray will cause law suit.
D、We should use MRI instead of X-ray.
答案A
解析 推理题。由原文可知，美国杜克大学的医生警告说仅依靠标准X光检查身体，有可能会导致错误的诊断和法律诉讼。由此可以推知，不能一直依赖X光。故选A。
