Understanding and using teleradiology.

In 1972, Webber and his coauthors closed their landmark paper with some visionary remarks that have proved to be remarkably perceptive. They hypothesized that special telephone circuits or radiofrequency channels could be used to yield "images whose grey scale and resolution are satisfactory enough to be virtually indistinguishable from the original." Speaking of transmitting still-frame images in a reasonable length of time and at a reasonable cost, they were limited by the current state of technology, but not by failing to use available technology creatively. We now have the tools they lacked; we must analyze alternatives and apply them. First, define the clinical problem. Determine the minimum acceptable function level of the proposed teleradiology system. Then use your best judgement to sort our convenience, reliability, cost, and various other considerations in light of the needs of your practice. As you develop the scenario, frequently refocus on the problem to be solved. Very likely you will find, as you look closer at current options, that by using teleradiology you could increase the quality of service to your patients by extending your presence electronically to areas where constant physical presence is simply not possible, affordable, or convenient.
