Normal Variants of a Photon-Deficient Area in the Lower Sternum Demonstrated by Bone SPECT

Abstract

Differentiation from malignancy appears to be related to lesion symmetry, location, midline, and evenly distributed radioactivity surrounding the edge of the photopenic area.

Pitfalls and Limitations of Radionuclide Planar and Hybrid Bone Imaging

“…9A) has been reported in 9% of patients on planar and in 30% of patients older than 30 years using SPECT. 14,15 It is important to note the location and nature of these focal variants in the sternum as they are usually central in location and often show a regular outline. 14 Generally, in elderly patients, a segmented appearance corresponding to the anatomical segments is seen (Fig.…”
