Decision aids in radiology.

Computer systems can help radiologists decide which tests to perform and which diagnoses to consider. Repositories of clinical data and general medical knowledge can provide information on demand for decision-making tasks; many of these information resources are available remotely via the Internet. Decision support systems can incorporate the techniques of artificial intelligence to apply their general knowledge to the features of a particular patient. Successful use of these technologies requires careful attention to design, implementation, and rigorous evaluation. Computer-based decision aids can improve the cost effectiveness and diagnostic accuracy of radiologic practice and are poised to play an important role in the future of radiology.
