Interpretation of roentgenograms via interactive television.

The diagnostic quality of roentgenographic images transmitted by interactive television was evaluated. A series of 100 kidney, ureter and bladder, chest, and bone radiographs were read individually by five radiologists, both on direct viewing and on viewing a monitor image of the television signal. The latter was transmitted by microwave a distance of 28 miles, including four transmission legs. Analysis in terms of receiver operating characteristic curves and critical tables indicated that the television interpretations were of acceptable accuracy, in view of the participants' inexperience with teleradiology.
