Thyroid Uptake Probe

A Thyroid Uptake Probe is a gamma detection instrument used to measure how much radioiodine (I-131 or I-123) the thyroid gland absorbs. It is used mainly for functional assessment, not imaging.

How It Works

The probe contains:

✔ Sodium Iodide (NaI(Tl)) scintillation crystal

Detects gamma photons.

✔ Collimator (usually flat-field or pinhole)

Ensures only radiation coming from the thyroid region is measured.

✔ Photomultiplier Tube (PMT)

Converts light signals to electrical signals.

✔ Counting system / Electronics

Gives counts per minute (CPM) or percentage uptake.

The patient is given a small oral dose of radioiodine → the probe measures thyroid vs background → the system calculates % uptake.

What It Measures

➤ Radioactive Iodine Uptake (RAIU)
• 2-hour uptake
• 24-hour uptake (most important)

This value reflects thyroid iodine trapping and organification activity, helping diagnose:
• Hyperthyroidism (e.g., Graves’ disease, Toxic nodules)
• Hypothyroidism
• Thyroiditis
• Effectiveness of antithyroid medications

Advantages
• Quick
• Non-invasive
• Low radiation
• High sensitivity for thyroid function
• Inexpensive compared to imaging (thyroid scan)

Typical Normal Values

I-131 / I-123 RAIU
• 2-hour: 5–15%
• 24-hour: 10–30%
(Varies slightly between departments)

Clinical Uses
• Differentiate Graves’ disease vs thyroiditis
• Pre-therapy dosimetry for I-131 in hyperthyroidism
• Calculate administered activity for thyroid cancer ablation (less common)
• Evaluate iodine deficiency/excess
