Diagnostic radiology is one of the key areas of clinical diagnosis on which much of the health care system is built. Along with pathology, radiology has a unique role in providing diagnostic information for prognosis, treatment, and management of clinical conditions. This role is clinically challenging due to the problems of knowledge management associated with the free-text radiology reports which are currently the standard of practice for radiology care.
