Can a renal scan show damage in your lungs or goiter on thyroid?

No. A renal scan is a specialized medical imaging procedure used to evaluate the structure and function of the kidneys. It involves injecting a radioactive tracer into the bloodstream, which is then taken up by the kidneys and excreted into the urine. The images obtained during a renal scan provide detailed information about the size, shape, and blood flow to the kidneys, as well as any abnormalities or damage within them.

Damage in the lungs or a goiter on the thyroid are not conditions that can be detected or assessed using a renal scan. These issues would typically require different imaging techniques, such as a chest X-ray for lung evaluation or an ultrasound or thyroid scan for assessing the thyroid gland.
