目的：研究DR和CT对老年人腰椎退行性病变的临床诊断价值。方法选择2011年3月-2013年3月治的480例患者进行研究。按照随机数表法，随机分别为DR组和CT组，每组各240例患者。分别采用DR、CT对两组患者进行诊断，并对两组患者诊断的影像学特点和准确率进行比较分析。结果480例患者共有270例患者出现老年腰椎间盘突出，在小关节处均出现不同程度退变现象。其中DR组患者的误诊、漏诊共有9例，而CT组没有出现误诊、漏诊；CT组对于各类老年腰椎退行性病变的临床诊断效果明显优于DR组（P<0.05）。CT组诊断的确诊率明显高于DR组（P<0.05）；CT组诊断的误诊率和漏诊率(0)均明显低于DR组（2.08%,1.67%），两组比较有统计学意义（P<0.05）。结论应用CT扫描的方法诊断老年腰椎退行性变更清晰准确，效果优于DR。

Objective To study the diagnostic value of DR and CT in the elderly lumbar degenerative disease . Methods 480 patients from March 2011 to March 2013 were studied and were divided into to DR group and CT group in according with the table of random numbers, 240 in each patients. The two groups were diagnosed with DR and CT respectively. The imaging features and the accuracy rate of diagnosis were compared. Results 270 patients were elderly lumbar disc, there are different degrees of degeneration in the small joints. There were 9 cases in DR group with misdiagnosis, and there was no misdiagnosis in . the imaging features of advantage of the CT group better than the DR group The assurance of diagnosis in CT group for all types of elderly patients with lumbar degenerative disease is better than the DR group, the data was statistically signiifcant (P<0.05). Diagnosis rate of the CT group was signiifcantly higher than the DR group (P<0.05);misdiagnosis and missed diagnosis rate of the CT group (0.0%) were signiifcantly lower than the DR group (2.08%, 1.67%), the differences was statistically signiifcant (P<0.05). Conclusion It is clear and accuracy that CT was used in the diagnosis for the elderly lumbar degenerative.It is better than DR.
