Conventional screen-film radiographs were compared with storage phosphorus images concerning diagnostic performance in traumatologic radiography. We used an image pool of 106 radiographs including 50 conventionally and 56 digitally recorded images. The images were reviewed by four experienced radiologists. Detectability of fractures was coded in a five-point scale of confidence and analysed by ROC statistics. Furthermore the image quality and the optical density was compared. Digital images are superior under difficult exposure conditions and offer advantages by additional image processing and documentation. For some indications (follow-up, functional examination), reduced x-ray exposure is tolerable. The detectability of subtle lesions, which is essential for the primary diagnosis of fractures was significantly better by conventional radiography.
在创伤放射学中,将传统的屏-片X线摄影与存储磷光体成像的诊断性能进行了比较。我们使用了一个包含106张X线片的图像库,其中包括50张传统记录的和56张数字记录的图像。这些图像由四位经验丰富的放射科医生进行评估。骨折的可检测性采用五点置信度量表进行编码,并通过ROC统计分析。此外,还比较了图像质量和光学密度。在困难的曝光条件下,数字图像表现更优,并且通过额外的图像处理和存档具有优势。对于某些指征(随访、功能检查),减少X线曝光是可以接受的。对于骨折的初步诊断至关重要的细微病变的可检测性,传统X线摄影明显更好。
