Personal computer teleradiology: comparing image quality of lateral cervical spine radiographs with conventional teleradiology.

Teleradiology images of 14 cervical spine x-rays were studied by radiologists to compare radiological diagnostic interpretations and image quality with an inexpensive personal computer (PC) teleradiology system adapted to personal computers. Image quality ratings were similar for the conventional teleradiology images, PC teleradiology images, and the original cervical spine films. Interpretations of images showed some variation between PC and conventional teleradiology. Lesions in poorly contrasted films were visible with difficulty, using PC teleradiology. Lesions in well-contrasted films were identified easily with all three image types. Inexpensive teleradiology can be achieved using PC devices already on the market for $650 to $2000 compared with $30,000 for conventional teleradiology. Standardization of image and modem transmission parameters may facilitate the development of interhospital image transfers to optimize patient transfers and to assist in long-distance patient consultations. PC teleradiology deserves further study.
