During which imaging technique does dynamic and whole-body scanning occur after 5 minutes?

The correct choice is associated with 11C-Sodium Acetate imaging, which involves dynamic and whole-body scanning that typically occurs around 5 minutes post-injection. This timing is particularly significant because 11C-Sodium Acetate is a radiotracer commonly used to assess myocardial metabolism and perfusion, especially in the context of cardiovascular research.

In this imaging technique, the rapid uptake of the tracer allows for an early assessment of tissue metabolism, and the dynamic phase captures changes in tracer distribution over a short time interval, which is vital in evaluating organ function and blood flow. The use of sodium acetate provides clear images shortly after administration because it is rapidly incorporated into metabolic pathways, making it ideal for both dynamic and whole-body imaging scenarios where timely information is crucial.

Other imaging techniques listed may involve different timing or characteristics that do not align with the dynamics and rapid whole-body scanning described in the question. Understanding the unique traits of each imaging modality is key to differentiating them effectively.
