| 摘 要： | 目的:评价不同分辨率的单色液晶显示器对胸部DR影像图上病灶检出效能和细节显示质量的影响。方法:从PACS中在线选取胸部DR影像图93幅,其中由阳性图38幅、疑诊图32幅、正常图23幅组成,将阳性病例按结节尺寸大小分为A、B两组,请高、中、低年资医师各3名在3种不同分辨率的显示器上3次独立读图。对于结节显示有无的评判采用5等分法:肯定有、可能有、不确定、可能无、肯定无,对于纹理显示质量优劣的评判采用3等分法:优、良和差。使用SPSS13.0对结果进行统计分析。结果:病灶检出效能:高年资医师使用2MP、3MP、5MP显示器识读A组结节时AUC分别为0.643、0.686、0.739,中年资为0.636、0.682、0.717,低年资为0.623、0.656、0.621;识读B组结节时高年资医师为0.813、0.832、0.846,中年资为0.773、0.824、0.838,低年资为0.763、0.773、0.833;不同放射诊断系统间病灶检出效能比较差异无统计学意义。细节显示质量:除在5MP显示器上高和中年资医师、高和低年资医师之间存在显著性差异(P0.05)外,其他比较差异均无统计学意义。结论:对于结节检测效能而言,不同放射系统之间诊断效能相当;对于纹理显示质量而言,高年资的医师在5MP显示器上能得到更多的信息。 |

| Abstract: | Objective:Evaluate the influence of monochrome LCDs with different resolutions for the quality of detail imaging and detection performance of lesions. Methods:93 DR chest images were selected from PACS on-line,including 38 positive cases,32 suspected cases and 23 normal cases. The positive cases were divided into two groups A and B according the diameter of pulmonary nodules. Three of high-,mid-and low-experienced radiologists interpreted the 93 images on three types of displays independently. Each observer... |
