These tracers aren't dyes or medicines, and they have no side effects. The amount of radiation a patient receives in a typical nuclear medicine scan tends to be very low.

How long are you radioactive after a scan?

How do you get rid of radiation from a CT scan?

Reporting at the annual meeting of the Society of Interventional Radiology, Dr. Kieran Murphy, a radiologist at the university, said that a cocktail of antioxidants he and his team have developed could cut the damage done to DNA by radiation from CT scans by as much as 50%, if taken before the scan.

Is radioactive dye harmful?

Radioactive dye is injected into the body to capture images of internal structures and to look for abnormalities. The radioactive nature of the dye is the main reason why some patients feel uneasy about undergoing the procedure. However, the test is primarily safe, and there are rarely any associated complications.

How long does iodine contrast stay in your system?

But some side effects may continue after treatment is over because it takes time for healthy cells to recover from the effects of radiation therapy. Late side effects can happen months or years after treatment.

Is radiation worse than chemo?

What do they inject you with for a stress test?

In the nuclear stress test with exercise, a radionuclide, such as thallium or technetium, is injected into a vein in the hand or arm. When the radionuclide has circulated through the blood stream, a gamma camera takes pictures of the heart while the patient is lying down. This is known as the “rest scan” of the heart.
