Therefore, physicians cannot easily ignore the diagnoses made by the new imaging techniques, McEvoy said, "We are left with the dilemma 4 of what to do with the results,"According to McEvoy, doctors should focus on patients' lifestyle and traditional risk factors such as smoking and obesity 5.(本文由在线英语听力室整理编辑)
