title: Introduction to evidence-based imaging.
abstract: Society is increasingly demanding proof that imaging has an impact on patient outcome and questioning its cost on the health care delivery system. Radiologists should provide the following three key components in their research publications: (1) the statistical power and confidence intervals of the results obtained; (2) the diagnostic performance of the tests, including sensitivity, specificity, and ROC curves; and (3) comprehensive decision analysis and cost-effectiveness analysis to determine the impact that imaging has on health outcome, cost, and quality of life. Strict adherence to these evidence-based medicine principles would help advance the field and provide the best health care for patients.
