Multiple authors have pointed out the difficulty of detecting spondylolysis with lumbar CT. A simple method to detect spondylolysis on lumbar CT is described. Identifying one intact cortical ring for each vertebra absolutely excludes the diagnosis obviating the time-consuming need to search each image looking for positive evidence of the abnormality. If at least one intact cortical ring for each vertebra is not found, a defect in the ring at the appropriate position assures the diagnosis.
多位作者指出了通过腰椎CT检测椎弓根峡部裂的困难。本文描述了一种在腰椎CT上检测椎弓根峡部裂的简单方法。为每个椎体识别一个完整的皮质环可绝对排除该诊断，从而无需耗时地在每张图像上寻找异常的阳性证据。如果未找到每个椎体至少一个完整的皮质环，则在适当位置的环缺损可确诊。
