[originaltext] US doctors from Duke University warn that relying on standard

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?
