The specialist will likely have you drink a contrast material, which will highlight organs, muscle tissue and blood vessels, as the X-ray images won’t show them clearly.

What are the benefits of using iodine 123?

The gamma emission of 123I allows excellent imaging (≈80% efficiency for a ½-inch-thick crystal) with low background activity. It provides considerably lower doses of radiation to the thyroid with comparable activity than does 131I. Iodine-123 is the iodine of choice for thyroid imaging (Fig.

How will I feel after Thyrogen injection?

How long does Thyrogen injection stay in your system?

The pharmacokinetics of Thyrogen were studied in 16 patients with well-differentiated thyroid cancer given a single 0.9 mg IM dose. Mean peak concentrations of 116 ± 38 mU/L were reached between 3 and 24 hours after injection (median of 10 hours). The mean apparent elimination half-life was 25 ± 10 hours.

How does iodine-123 leave the body?

What happens to the radioactive iodine after it enters my body? Most of the I123 your thyroid tissue does not absorb will leave your body in your urine and stool. The rest will simply decay over time.
