A parathyroid MIBI scan is a nuclear medicine imaging test that localizes overactive parathyroid tissue (typically adenomas) before surgery. It uses a radiotracer (technetium‑99m sestamibi) injected into a vein, with early and delayed images to detect glands that retain tracer. It helps guide minimally invasive surgery; accuracy varies with gland size and multigland disease. Pregnancy and breastfeeding require precautions.

A nuclear medicine parathyroid scan uses a small injected radioactive tracer (commonly technetium-99m sestamibi) and a gamma camera to localize overactive parathyroid tissue. It helps detect adenomas or hyperplasia in patients with suspected primary hyperparathyroidism and guides surgical planning. The scan is noninvasive, involves early and delayed images, and typically takes a few hours including uptake and imaging.

Costs vary by country and provider: India about ₹2,000–10,000; UK private £200–700 (NHS usually free for eligible patients); US typically $300–3,000 out-of-pocket depending on facility and insurance. Exact price depends on region, whether single- or dual-tracer/SPECT-CT, and insurance coverage—contact your imaging center or insurer for a precise quote. Prices reflect imaging type, local demand, and any additional reporting or sedation fees.

A nuclear parathyroid scan is generally safe. Possible side effects: mild injection‑site pain, bruising or warmth; transient nausea, headache, dizziness, itching or flushing; rare allergic reactions (very rarely severe anaphylaxis). There is small additional radiation exposure, so scans are avoided in pregnancy and used cautiously in breastfeeding. Serious complications are uncommon; report any unexpected symptoms to your provider.

A 99mTc-sestamibi (MIBI) scan is generally safe for most people. It uses a small amount of radioactive tracer; side effects are rare and usually mild (injection-site pain, transient nausea or allergic reactions). Pregnancy is avoided unless essential, and breastfeeding may require temporary interruption. Inform your provider about kidney problems, allergies, or pregnancy to minimize risks.

A parathyroid scan is used to detect and localize overactive parathyroid tissue that causes high calcium (hyperparathyroidism). It distinguishes single adenomas from multigland disease, identifies ectopic glands, guides surgical planning for targeted or minimally invasive removal, and assesses persistent or recurrent disease after prior surgery. Accurate localization improves surgical success and reduces operative time.
