Nucs agents CORE - Sheet1 Flashcards
mechanism: MDP
phospate analog - chemisorption
mechanism: Free Xe-133
not absorbed (inspired) - can diffuse into fat
mechanism: MAA
albumin - gets stuck in capillary (10-100 microns)
mechanism: sulfur colloid
phagocytized by RES
mechanism: HIDA
bilirubin analog
mechanism: WBC
tagged neutrophil - goes to RES or active inflammation
mechanism: RBC
tagged RBC - circulated in blood
mechanism: MAG-3
actively secreted
mechanism: DMSA
binds to sulhydryl group in proximal tubule
mechanism: pertechnetate
active transport in thyroid

active transport
mechanism: thallium 201
potassium analog, active transport (Na/K pump)
mechanism: pentreotide
analog of octreotide
mechanism: MIBG
analog of norepinephrine - enters neuroendocrine cells by active uptake mechanism via epinephrine transporter and is stored in neurosecretory granules
