The purpose of this exhibit is to: 1. Review the major biostatistical considerations in diagnostic imaging. 2. To apply these concepts to the everyday clinical practice of the radiologist: diagnostic testing, screening, and radiation risk. 3. To apply fundamental biostatistical concepts to aspects of radiology research. 4. To provide the busy radiologist with a free and easy to access online reference for use whenever these concepts may be encountered. 

Biostatical considerations in diagnostic testing - Specificity and sensitivity - Positive and negative predictive values - Receiver operating characteristic (ROC) curve Biostatistical considerations in screening - Relative risk reduction, absolute risk reduction, number needed to screen, and survival (disease-specific and all-cause mortality) - False positives and false negatives - Pseudodisease and overdiagnosis Biostatistical considerations in radiation biology Biostatistical considerations in radiology research Illustrative cases and examples Summary

The major teaching points of this exhibit are: 1. To review the major biostatistical considerations in diagnostic imaging. 2. To provide the busy radiologist with a free and easy to access online reference for use whenever these concepts may be encountered.
