| 目的 探讨基于虚拟双能量减影软组织胸片生成技术计算机辅助检测肺结节的应用价值。方法 收集日本放射技术学会(JSRT)数据库中经CT检出的肺结节126个,对比虚拟双能量减影软组织胸片及未结合虚拟双能量减影软组织胸片对肺结节的检出率。结果 结合虚拟双能量减影软组织胸片生成技术,辅助检测系统,在平均每幅图4.5个假阳性水平下可检出80.16％(101/126)的结节;未结合虚拟双能量减影软组织胸片的原检测系统,在平均每幅图4.5个假阳性水平下检出72.22％(91/126)的结节。结论 基于虚拟双能量减影软组织胸片生成技术计算机辅助检测有助于提高肺结节检出率。 |

| Objective To discuss the application value of lung nodules computer-assisted detection based on virtual dual energy subtraction soft-tissue radiography generation technology. Methods Totally 126 lung nodules detected by CT were collected from Japan Institute of Radiological Technology (JSRT) database. The detection rates of lung nodules detected using virtual dual energy subtraction soft tissue chest radiography or not were compared. Results At the average of 4.5 false positive level per image, the detection rate of lung nodules was 80.16% (101/126) based on virtual dual energy subtraction soft-tissue images, while the detection rate was 72.22% (91/126) without virtual dual energy subtraction soft-tissue radiography generation technology. Conclusion Virtual dual energy subtraction soft-tissue radiography generation technology is helpful to improve the detection rate of lung nodules. |
