摘要
Tc-99m methylene diphosphonate bone scintigraphy was performed to evaluate for metastases in a 55-year-old man with advanced gastric cancer. Diffuse increased tracer uptake was noted in the right radius proximal to a tourniquet application for intravenous radiotracer injection. A plain radiograph showed no abnormality. On the follow-up bone scintigraphy performed 2 days later, no abnormal uptake was detected in the right radius. The first increased tracer uptake was suggested to be an injection artifact which appeared in the long bone proximal to the tourniquet application, and should be differentiated from true bone lesions.
