May 25, 2021 · In a typical thyroid scan, a nuclear imaging test will be performed using small amounts of radioactive material to look at the size, position, and shape of the thyroid. X Research source During a thyroid uptake, also known as a radioactive iodine uptake test, you’ll swallow iodine as a liquid or capsule so your thyroid function can be ...
RAIU is a type of nuclear test that measures how much radioactive iodine is taken up by the thyroid gland in a given time period. You are asked to ingest (swallow) radioactive iodine (I-123 or I-131) in liquid or capsule form. After a time (usually 6 and 24 hours later), you must return to have the radioactivity measured.
Nov 8, 2023 · This test may help diagnose autoimmune thyroid disorders. Imaging tests include: CT scans; Ultrasound; Nuclear medicine tests, including: Thyroid scan. It uses small amounts of radioactive material to create a picture of the thyroid, showing its size, shape, and position. It can help find the cause of hyperthyroidism and check for thyroid ...
Jan 7, 2023 · A nuclear stress test is an imaging test that shows how blood goes to the heart at rest and during exercise. It uses a small amount of radioactive material, called a tracer or radiotracer. The substance is given by IV. An imaging machine takes pictures of how the tracer moves through the heart arteries. This helps find areas of poor blood flow ...

Feb 24, 2024 · A thyroid uptake test is another name that is used to describe an RAIU test. An RAIU is a nuclear test that works by detecting molecular activity. Using radioactive material, the test can ...
Radioactive iodine uptake test is a type of nuclear test performed to evaluate thyroid function. The patient ingests radioactive iodine (I-123 or I-131) capsules or liquid. After a time (usually 6 and 24-hours later), a gamma probe is placed over the thyroid gland to measure the amount of radioiodine uptake in the thyroid gland.
