We evaluated the clinical utility of high data compression for computed radiography (CR) of the hand. Paired original and compressed CR images were obtained using an FCR 9000 system in 35 patients with various abnormalities of the hand. For the paired original and compressed images, we compared the depiction of the bone cortex, bone trabeculae, soft-tissue, and the margin of the abnormalities. The overall impressions for detectability of the abnormalities and for diagnostic capability were also evaluated. Poorer image quality of the compressed images was noted for most of the structures, but there was no significant difference between the original and compressed images as for the overall impressions for detectability of the abnormalities or for diagnostic capability. We conclude that a high data compression may be clinically acceptable with caution in radiography of the hand.
我们评估了手部计算机X线摄影（CR）中高数据压缩的临床实用性。使用FCR 9000系统，为35名患有各种手部异常的患者获取了成对的原始CR图像和压缩CR图像。对于成对的原始图像和压缩图像，我们比较了骨皮质、骨小梁、软组织以及异常边缘的显示情况。还评估了对异常可检测性和诊断能力的总体印象。大多数结构的压缩图像质量较差，但在异常可检测性或诊断能力的总体印象方面，原始图像和压缩图像之间没有显著差异。我们得出结论，在手部X线摄影中，谨慎使用高数据压缩在临床上可能是可以接受的。
