举例来说，如果不用核磁共振成像扫描和计算机层析成像扫描，而用简单的血液检查能够查出严重疾病，那就能节省费用和医疗资源。

For example, if asimple blood test could be developed to rule out a serious problem without anMRI or a CT, it would save loads of money and resources.

公平地来说，CT（计算机层析成像扫描）的检查结果通常比高级外科医生的诊断观点更为正确，对于病人们也更具有意义，因为你总是希望医生在给你做手术前有百分百的把握。

In fairness, CT results can be often better than even a senior surgeon'smedical opinion. It also makes sense for patients: you want your surgeon to bedarn sure before they operate on you.
