In the article “An Introduction to Na18F Bone Scintigraphy: Basic Principles, Advanced Imaging Concepts, and Case Examples,” by Bridges et al. (J Nucl Med Technol. 2007;35:64–76), the legends of Figure 1 (which is also the cover image) and Figure 6E mistakenly describe the image as having been obtained with 18F-FDG instead of with the correct tracer, 18F. We regret the error.
