Neuroimaging of Cerebral Vessels: Evidence-based Medicine in the Evaluation of Acute Stroke and Aneurysm Detection

  • M. E. Jensen


As neuroimaging becomes more complex and widely available, the cost of health care is rising rapidly for both the individual and society as a whole. A continuous flow of medical literature makes it difficult to elucidate the true science from the merely descriptive. The current trend towards evidence-based medicine is an attempt to find those diagnostic and therapeutic imaging studies that provide the best information at the most reasonable cost. The best information comes from randomized controlled trials that are prospectively designed to determine performance and efficacy (Level 1 evidence) [1]. It is more likely, however, that Level 2 (clinical non-randomized studies, cohort and case-controlled studies, uncontrolled prospective studies) or Level 3 (descriptive studies, case series, expert committee reports) evidence will be more readily available. Readers are referred to the recent Neuroimaging Clinics of North America monograph [2] for more in-depth information. A synopsis of the evidence-based medicine as it pertains to the neuroimaging of common clinical conditions follows here.
