Correctly using sensitivity, specificity, and predictive values in clinical practice: how to avoid three common pitfalls

AJR Am J Roentgenol. 2013 Jun;200(6):W566-70. doi: 10.2214/AJR.12.9888.

Abstract

Objective: Radiology is the specialty of imaging-based diagnostic tests. Understanding the science behind evaluating diagnostic test performance is essential for radiologists because we provide care to patients and interact with our colleagues.

Conclusion: Here, we review the key terminology used and common pitfalls encountered in the literature and in day-to-day discussions of diagnostic test performance.
