After total thyroidectomy, total body imaging with radio iodine will typically demonstrate tracer concentration in which areas?

After total thyroidectomy, total body imaging with radioactive iodine (RAI) will typically show tracer concentration in areas where the iodine is taken up or concentrated. In the context of the options provided, the salivary glands, stomach, and bladder are known to accumulate radioactive iodine due to their physiological functions.

Salivary glands can concentrate iodine as they are involved in salivary production and metabolism. The stomach can also concentrate iodine due to its secretory cells, which can uptake iodine as part of their function. Lastly, the bladder is where radioactive iodine will be excreted, demonstrating tracer concentration as the isotope is eliminated from the body.

This physiological behavior highlights the body's mechanisms in handling iodine after total thyroidectomy, where other uptake sites related to thyroid tissue are removed, and these organs represent relevant physiological sites.

The other options refer to tracer concentrations in areas that do not typically demonstrate significant iodine uptake following RAI administration after thyroidectomy.
