| 目的 探讨双能减影对肋骨病变的诊断价值。方法 收集200例病人行胸部数字化X线摄影(DR)双能减影,对双能减影后胸廓的肋骨像与胸部的肋骨像进行对比分析,采用5阶法行ROC曲线解析。结果 200例中肋骨钙化50例,肋骨破坏7例,肋骨骨折22例。双能减影的胸廓肋骨像的ROC曲线解析参数(Az=0.9367),大于胸部肋骨像的解析参数(Az=0.6830)。结论 胸部DR双能减影对肋骨病变及膈下肋显示明显优于胸部的肋骨像。 |

| Objective To investigate the application value of DR dual energy subtraction technology in rib lesions. Methods 200 patients were performed with chest DR dual energy subtraction, comparing the rib imaging between DR of thorax and chest imaging using ROC analysis. Results Among the total of 200 patients, there are 50 cases of rib calcification,7 cases of rib destruction,22 cases of rib fracture. The calcification, destruction and fracture were displayed respectively by ribs below diaphragm and rib markings. The analytic parameter of rib imaging of DR dual energy subtraction Az is 0.9367, while that of rib imaging of chest Az is 0.6830. Conclusion DR dual energy subtraction technology is superior to chest imaging in the displaying of rib lesion and ribs below diaphragm. |
