The scans were performed with a parallel high-resolution low-energy collimator at an energy setting of 140 KeV photo peak for Tc-99 m. The scan was done 20 min after the intravenous administration of 75–90 MBq Tc-99 m pertechnetate. The patient is positioned supine with the chin up and the neck extended. The RAIU test is also used as a follow up to RAI therapy to verify that no thyroid cells survived, which could still be cancerous. This is known as a thyroid function test. The test checks the levels of: thyroid-stimulating hormone (TSH) – a hormone produced by the pituitary gland (a gland at the base of the brain) which controls the production of thyroid hormones triiodothyronine (T3) – one of the main thyroid hormones.
