Remote interpretation of chest roentgenograms

Area of Science:

• Medical Imaging
• Radiology
• Telemedicine

Background:

• Traditional radiology relies on direct interpretation of physical films.
• Increasing demand for radiologic services necessitates exploring remote diagnostic capabilities.

Purpose of the Study:

• To evaluate the diagnostic accuracy of interpreting chest roentgenograms via television transmission compared to direct film viewing.
• To assess the feasibility of using telemedicine for remote radiological interpretations.

Main Methods:

• Two physicians interpreted 98 chest films using monitor display of transmitted television signals.
• Interpretations were compared to classic, direct-view interpretations of the same films.
• Receiver operating characteristic (ROC) curves were used for performance comparison.

Main Results:

• Interpretation performance was similar between television display and direct film viewing.
• When ambiguous hazy densities were excluded, interpretations were virtually identical between the two modes.
• The 14-mile transmission with a repeater station did not significantly impair diagnostic accuracy.

Conclusions:

• Interpreting roentgenograms at a distance via television is a feasible method for delivering radiology services.
• This approach can potentially expand access to expert radiological interpretations, especially in underserved areas.
• Further research into the impact of image quality and different transmission methods is warranted.
