OBJECTIVE
To assess whether the quality of x ray films transmitted via a low cost (low resolution) telemedicine link was satisfactory for clinical diagnosis.
METHODS
A retrospective study of a set of consecutive accident and emergency (A&E) radiographs. An A&E registrar viewed these directly on a standard x ray viewing box and via a telemedicine link.
RESULTS
There were 81 abnormalities out of 234 x ray films. Three abnormalities were missed both on the x ray viewing box and telemedicine link, one of which was significant. There were five additional abnormalities missed on the telemedicine link but detected on the x ray viewing box, of which two were significant. One normal x ray film was interpreted as abnormal on the telemedicine link. There were no false positives on direct viewing.
CONCLUSION
Transference of plain radiographs using a low cost/low resolution telemedicine link by A&E doctors is adequate for clinical interpretation.
目的
评估通过低成本（低分辨率）远程医疗链路传输的X光片质量是否足以满足临床诊断需求。
方法
对一组连续的急诊X光片进行回顾性研究。一名急诊住院医师直接在标准X光阅片箱上以及通过远程医疗链路查看这些片子。
结果
234张X光片中发现81处异常。有3处异常在X光阅片箱和远程医疗链路上均被漏诊，其中1处为重大异常。另有5处异常在远程医疗链路上漏诊但在X光阅片箱上被发现，其中2处为重大异常。有1张正常X光片在远程医疗链路上被误诊为异常。直接阅片时未出现假阳性情况。
结论
急诊医生通过低成本/低分辨率远程医疗链路传输普通X光片足以用于临床解读。
