Comparative Effectiveness Research Award
This award was created to support investigators in the generation and synthesis of evidence that compares the benefits and harms of diagnostic imaging methods or interventions to prevent, diagnose, treat and monitor a clinical condition or to improve the delivery of care. Comparative effectiveness research (CER) is valuable to clinicians, patients, purchasers, and policy makers in making informed decisions that will improve health care at both the individual and population levels. CER includes the direct comparison of diagnostic imaging modalities or interventions for a specific disease in a study population. Neuroradiologists have an important role in the development of new imaging technologies and image-guided procedures, as well as in the assessment of these techniques in the clinical care of patients.
