Static bone imaging is performed several hours after tracer administration to permit:

• A. Maximum tracer uptake in skeleton
• B. Blood clearance of excess tracer
• C. Tracer clearance from sites of infiltration
• D. Tracer clearance from normal bone tissue

Answer: (B)

Static bone imaging is performed several hours after tracer administration to allow for adequate blood clearance of excess tracer. This timing is crucial because it helps to reduce background noise and enhances the visualization of the areas of interest in the bone. After the administration of a radiopharmaceutical, the tracer initially circulates through the bloodstream and attaches itself to the bone, highlighting areas of increased metabolic activity or changes in bone structure. By waiting several hours, the body has had time to clear out the excess tracer from the bloodstream, which minimizes the activity from areas not relevant to the bone condition being assessed. This approach ensures a clearer and more focused image of the bones, making it easier to identify abnormalities or areas of pathology, such as tumors or fractures. Other choices mention various aspects of tracer behavior, but the key purpose of performing static imaging after several hours is primarily to improve image quality by allowing for effective clearance of background tracer from the blood circulation, which directly improves diagnostic accuracy.
