Can x rays be accurately interpreted using a low cost telemedicine system?
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.


CONCLUSIONS
Transference of plain radiographs using a low cost/low resolution telemedicine link by A&E doctors is adequate for clinical interpretation.
