Conventional tomography utilizes controlled blurring of overlying structures, in effect, to remove these possible obscuring overlying structures and permit improved evaluation of anatomic detail within the specific layer or focal plane of interest. Although it has largely been replaced by true sectional imaging modalities such as CT and MR imaging, it remains a valuable tool in specific settings as in musculoskeletal trauma. It is particularly useful when the orientation of the pathology requires coronal or sagittal planes for optimal evaluation.
传统体层摄影实际上是利用对重叠结构进行可控模糊处理,以去除这些可能造成遮挡的重叠结构,从而能够更好地评估特定感兴趣层面或焦平面内的解剖细节。尽管它在很大程度上已被CT和磁共振成像等真正的断层成像方式所取代,但在肌肉骨骼创伤等特定情况下,它仍然是一种有价值的工具。当病变的取向需要冠状面或矢状面进行最佳评估时,它特别有用。
