CAD no longer stands merely for computer-aided detection. Today's robust software programs make it possible to help characterize, or diagnose, nodules, particularly in the lungs. Current computer-aided technology favors detection, but the ability to diagnose lung nodules based on certain characteristics continues to develop rapidly. It's only a matter of time before computer-aided detection and computer-aided diagnosis become mainstay tools for pulmonary evaluation.
