Thyroroxicosis scintigraphy

Thyroroxicosis scintigraphy I-131 is produced in nuclear reactor (too many neutrons), beta minus decay. 364keV, half-life 8d I-123 is preferred agent now, produced in cyclotron (too many protons), electron capture, gamma emission, 159keV, half-life 13.2h, 18x more expensive than 1-131 Iodine 20% extrcate dby thyroid, 80% into urine Entrapment Organification Radioiodine I-131, I-123 Tc-99m Pertechnate, generator produced, 140keV photopeak, short half-life, lowest dose, IV, not organified F-18G RAIU - RadioActive Iodine Uptake Graves d: most common cause of thyrotoxicosis, TSAb (Thyroid stimulating Ab), 24h RAIU 80%; Marine-Lenhart: w/ cold nodules (nl tissue) TMNG: Toxic multinodular goite, patchy looking thyroid gland Toxic adenoma: autonomous nodule, always on, de Quervain Thyroiditis: thyrotoxicosisi due to viral damage to the gland, low uptake, initially thytotoxic then hypothyroid Amiodarone is #1 cause of med-induced thyrotoxicosis Struma ovarii
