What is an I 123 uptake and scan?

What is I-123 Uptake and Scan? An I-123 Uptake and Scan is a trace amount of radioactive iodine that is used to evaluate the thyroid gland for in physiological abnormalities. Patient Prep: Prior to the procedure the patient has to be off of all thyroid medication for. a minimum of 2 weeks.

What does a thyroid uptake scan show?

What is a Thyroid Uptake and Scan? A thyroid uptake and scan is a diagnostic imaging scan that allows the radiologist to determine the function of the thyroid. This scan can determine if the patient has thyroid cancer: persistent or recurrent disease, hyperthyroidism and thyroid nodule or goiter assessment.

What is a normal thyroid uptake percentage?

Normal and Critical Findings The normal values of thyroid uptake of radiotracer are 3 to 16% at 6 hours and 8 to 25% at 24 hours. These values may change according to laboratory standard techniques or patient dietary habits. The thyroid gland can uptake more or less than normal.

What does an abnormal thyroid uptake scan mean?

Abnormal: The test shows either more or less uptake of tracer than normal in the thyroid gland. If hyperthyroidism is present, abnormal test results may mean certain conditions are present.

Can I eat before thyroid uptake scan?

You will then need to wait 10 to 15 minutes before imaging begins. The entire visit takes about 1 to 1½ hours. If you are going to be treated with a therapeutic dose of I31 after the 24-hour uptake and scan, do not eat any solid foods for 2 hours before this appointment.

How long are you radioactive after a thyroid uptake scan?

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. A gamma probe is placed over the thyroid gland in the neck to measure the amount of radioactivity in the thyroid gland.

What is 24 hour thyroid uptake?

Another uptake is usually done 24 hours later. During the uptake, you lie on your back on a table. A device called a gamma probe is moved back and forth over the area of your neck where the thyroid gland is located. The probe detects the location and intensity of the rays given off by the radioactive material.

How can I tell if my thyroid is enlarged?

Examining your neck in the area of the Adam’s apple while you swallow can sometimes detect if your thyroid is enlarged. Swallow while tipping the head back, and examine your neck and the area above the collarbones. If you see any lumps or bulges, see a doctor.

How is a thyroid uptake and scan done?

Nuclear Medicine Exam Information Thyroid Uptake & Scan. This nuclear medicine exam is performed to evaluate the size, location, and overall functional level of the thyroid gland. The study is acquired using a small amount of radioactive iodine ( 123 I) that has no side effects due to radiation exposure.

When do you take the I 123 thyroid test?

Do not eat or drink for 2 hours prior to receiving the I 123 capsule (s) and for 2 hours after receiving the capsule. This test is done in 2 parts on 2 separate days. You will be asked to swallow a small amount of radioactive iodine (or tracer) in capsule form.

What is the CPT code for thyroid uptake and scan?

Division of Nuclear Medicine Procedure / Protocol. Thyroid Uptake and Scan (I-123, I-131, 99mTcO. 4. ) CPT CODE: Uptake (Single or Multiple) only 78012 UPDATED: June 2020 Uptake (Single or Multiple) & Scan 78014 Scan only 78013. Indications:

How is the uptake of iodine in the thyroid measured?

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.
