PURPOSE
To compared the diagnostic performance of low-dose (LD) lumbar-spine (L-spine) CT with that of standard-dose (SD) L-spine CT.
METHODS
Patients who underwent SD (n = 76) or LD (n = 68) L-spine CT using model-based iterative reconstruction were included. Two reviewers independently analyzed 10 anatomical regions on both CT scans. Also, suggested treatment decision between both CT scans was compared.
RESULTS
LD L-spine CT showed an excellent diagnostic accuracy (98.1-98.2%) that was comparable to that of SD L-spine CT (98.4-99.1%). The suggested treatment decision was not different between both CT scans.
CONCLUSION
LD L-spine CT can be used as a potential first-line diagnostic tool.
目的
比较低剂量（LD）腰椎CT与标准剂量（SD）腰椎CT的诊断性能。
方法
纳入使用基于模型的迭代重建技术进行SD（n = 76）或LD（n = 68）腰椎CT检查的患者。两名阅片者独立分析两种CT扫描上的10个解剖区域。此外，比较了两种CT扫描之间建议的治疗决策。
结果
LD腰椎CT显示出与SD腰椎CT（98.4 - 99.1%）相当的出色诊断准确性（98.1 - 98.2%）。两种CT扫描之间建议的治疗决策没有差异。
结论
LD腰椎CT可作为一种潜在的一线诊断工具。
