MEN syndrome je familiární onemocnění s autozomálně dominantním typem dědičnosti, pro které jsou typické změny v endokrinní funkci s tvorbou řady endokrinních tumorů. Většinou jde o benigní nádory s maligním potenciálem. MEN syndromy dělíme na MEN typu 1, 2A a 2B.

MIBG uptake was initiated by adding 15 mL of Dulbecco's modified Eagle medium containing 0.0037 MBq/mL (0.1 μCi/mL) 124 I-MIBG or 123 I-MIBG. Cells were harvested after a 15- to 240-min incubation period, and the activity ratio in the cell pellet and medium was measured in a Packard γ-counter (United Technologies). roendokrinních nádorů je možné teoreticky použít oba uve-dené principy, scintigrafie zobrazující rozložení somatostati-nových receptorů bývá však při detekci neuroendokrinních nádorů přesnější než scintigrafie po podání 123I-MIBG.

The following review aims to summarise contemporary information on I-131-meta-iodobenzylguanidine (I-131-mIBG) therapy in neuroblastoma being the most common paediatric extracranial solid cancer characterized by mIBG avidity in ≥90 % of patients. Pathophysiologic basis for mIBG uptake is the expression of the norepinephrine transporter on the tumor cell membrane. Meta Cardiac sympathetic dysfunction is closely associated with cardiac mortality in patients with chronic heart failure (CHF).

Dnes sú aj špecifickejšie spôsoby zobrazovania nádorového tkaniva neuroendokrinného pôvodu, a to jódom značkovaným metajodobenzylguanidínom ( 123 J-MIBG ) u nádorov Growing out of the International Dementia with Lewy Body Conference, held December 2015 in Fort Lauderdale, Florida, the updated criteria were co-authored by most leaders of this small global research community. The criteria elevate the importance of REM sleep disorder and incorporate the biomarker MIBG, among other changes. Although I‐MIBG scintigraphy is very useful for the diagnosis of LBD, many medicines, including tricyclic and tetracyclic antidepressants, have been reported to influence the MIBG uptake system. 5-7 I‐MIBG is an analog of guanethidine and is taken up by the presynaptic postganglionic nerve endings of the adrenergic nervous system.
