To evaluate a personal-computer-based teleradiology system for the interpretation of radiologic studies from an isolated community.
During a 5-month study period, 240 radiologic studies from the Grand Manan Hospital, Grand Manan, NB, were digitized and transmitted via telephone lines to the Saint John Regional Hospital, NB, for interpretation. The first 110 cases were interpreted with the use of a 1 K x 1 K monitor, and the remaining cases were interpreted with a 2 K x 2 K monitor. The teleradiology image reports were compared with the plain film reports for each case and discrepancies were identified. A panel reviewed all clinically significant discrepant cases to determine the source of the discrepancy.
There was 90.9% concordance between the teleradiology and plain film reports in the studies interpreted with the 1 K x 1 K monitor and a 88.4% concordance in the studies interpreted with the 2 K x 2 K monitor. Only 1.7% (4/240) of the discrepancies were attributed to an inadequate teleradiology digital image.
A personal-computer-based teleradiology system can be used to provide diagnostic imaging service of high quality to an isolated community.
评估一种基于个人电脑的远程放射学系统，用于解读来自偏远社区的放射学检查结果。
在为期5个月的研究期间，新不伦瑞克省大马南岛大马南医院的240份放射学检查结果被数字化，并通过电话线传输至新不伦瑞克省圣约翰地区医院进行解读。前110例病例使用1K×1K显示器进行解读，其余病例使用2K×2K显示器进行解读。将远程放射学影像报告与每个病例的平片报告进行比较，找出差异。一个专家小组审查了所有具有临床意义的差异病例，以确定差异的来源。
在使用1K×1K显示器解读的研究中，远程放射学报告与平片报告的一致性为90.9%，在使用2K×2K显示器解读的研究中，一致性为88.4%。只有1.7%（4/240）的差异归因于远程放射学数字图像质量不足。
基于个人电脑的远程放射学系统可用于为偏远社区提供高质量的诊断成像服务。
