2022.6.14 This test may be combined with a radioactive iodine scan to show a visual image of the uptake pattern. Ultrasound. Ultrasound uses high-frequency sound waves to produce images of structures inside the body. It can show if the thyroid gland is enlarged. It's most useful in people who can't undergo radioactive iodine uptake, such

The usual dose of radioactive iodine for a diagnostic whole body scan is 2–5 mCi. In comparison, the dose of radioactive iodine for a therapeutic administration RAI ranges from 30 mCi to up to 200 mCi. Administration

2023.7.31 I-123 is a radioisotope of iodine used for a thyroid uptake scan. By measuring the amount of radiotracer uptake, the RAIU study is able to identify the activity of the overall thyroid gland. In conjunction with clinical symptoms, blood work, and other imaging findings (such as ultrasound), and I-123 RAIU, or RAIU and thyroid scan, can

Test Overview. A radioactive iodine uptake (RAIU) test uses a radioactive tracer and a special probe to measure how much tracer the thyroid gland absorbs from the blood. The test can show how much tracer is absorbed by the thyroid gland. The RAIU test often is done along with a thyroid scan, which shows if the tracer is evenly spread in the gland.
Read MoreIn an untreated Graves patient, the whole thyroid gland will show up as hyper with a greater than normal uptake of the (mildly) radioactive iodine tracer. If you were untreated hypOthyroid your iodine uptake scan would show up darker, with little or Abnormally Low uptake of the iodine tracer. If you had a single "hot nodule" or hyper nodule ...

You will need to fast for 8 hours before taking the radioactive iodine uptake test. The first part of the test is swallowing radioactive iodine (I-131 or I-123) up to 24 hours before the test.

How the Test is Performed. You are given a pill that contains a tiny amount of radioactive iodine. After swallowing it, you wait as the iodine collects in the thyroid. The first uptake is usually done 4 to 6 hours after you take the iodine pill. Another uptake is usually done 24 hours later. During the uptake, you lie on your back on a table.

2023.8.15 Before you start the treatment, your doctor might ask you to prepare for treatment. This is to help any thyroid cancer cells in your body to take up the radioactive iodine. You might: have an injection or stop your thyroid hormone tablet to increase your levels of thyroid stimulating hormone. follow a low iodine diet before treatment.

00:00. 00:00. Radioiodine therapy is a nuclear medicine treatment. Doctors use it to treat an overactive thyroid, a condition called hyperthyroidism. They also may use it to treat thyroid cancer. When a small dose of radioactive iodine I-131 (an isotope of iodine that emits radiation) is swallowed, it is absorbed into the bloodstream.

Iodine can be made into two radioactive forms that are commonly used in patients with thyroid problems: I-123 (does not damage thyroid cells) I-131 (can be used to destroy thyroid cells) Both forms of RAI are given as a pill or liquid that you swallow. RAI is safe to use even if you have had an allergic reaction to seafood or CT contrast.

Here are some ways to minimize radiation risks to other people (and pets) after you have had RAI treatment: Stay at least six feet away from other people, including members of the public, family members, and co-workers, for three to 11 days. This means avoiding public transportation, hotels, carpools, and in some cases,
