目的：探讨X线数字断层融合技术( Digital Tomosynthesis，DTS)在腰椎峡部裂诊断中的应用价值。方法回顾本院49例经X线DR平片检查发现腰椎滑脱并进行DTS、64排CT检查的病例，对比三种检查的结果，分析每种检查各自的特点。结果49例中，DR发现椎弓峡部崩裂所致滑脱者36例，DTS、64排CT两者均发现椎弓峡部裂所致滑脱者46例，其中椎弓两侧峡部裂伴椎体滑脱44例，一侧峡部裂伴椎体滑脱2例；退变性所致滑脱者3例。结论 DTS检查与CT检查在发现峡部裂型腰椎滑脱的诊断方面价值相当，但其价格便宜，辐射剂量小，图像成像质量清晰，是可与CT相媲美的一项简单、有效的检查方法。

Objective To investigate the X-ray digital tomosynthesis (Digital Tomosynthesis,DTS) in the diagnosis of lumbar spondylolysis. Methods 49 cases reviewed by X-ray DR plain film revealed spondylolisthesis and DTS,64 slice CT examination of cases,the comparison of the three test results,analysis of its characteristics.Results In 49 cases,36 cases of vertebral spondylolisthesis spondylolysis induced was found by DR,46 cases of vertebral arch spondylolysis induced detachment was found in DTS and 64 slices of CT,the vertebral arch on both sides of spondylolysis and spondylolisthesis in 44 cases,unilateral spondylolysis and spondylolisthesis in 2 cases;3 cases of degenerative spondylolisthesis.Conclusion DTS examination and CT examination in the diagnosis of discovery that have the same value for lumbar isthmic spondylolisthesis,but its price is cheap,the radiation dose is small, the quality of imaging is clear,is a simple,effective inspection method can be comparable with the CT.
