Abstract

Objective: To describe the normal appearance of the sternal area on bone scintigraphy. Methods: 120 patients, who did not have symptoms of the sternum or a history of malignancy, underwent whole-body bone scan and were evaluated for characters of sternal uptake. Results: ①In pediatric patients, their character was similar, and sternal uptake was homogeneous. In other patients, the sternum showed markedly different, and seven different patterns of sternal uptake were noted. ②The most common hot spot was at the angle of Louis, and there was focal spot of decreased tracer uptake in the lower sternum. Conclusion: This study showed age-related normal variants of sternal uptake. Understanding these variants may be helpful in differentiating normal and abnormal patterns of uptake in the sternum on radionuclide bone imaging.
