Co je mibg

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. Výjim-kou je pátrání po neuroblastomu, paragangliomu a feochro-mocytomu (1, 2).

Similar to cytotoxic chemotherapy with cyclophosphamide, vincristine, and dacarbazine, MIBG can induce remission for a limited period in a significant proportion of patients. Octreotide as a single agent seems to be largely ineffective. Therefore, 124 I‐mIBG PET/CT is expected to improve image quality and/or may be used to reduce effective patient dose as compared with 123 I‐mIBG SPECT/CT. 124 I‐mIBG activities as low as 3.7–48 MBq are recommended, depending on the weight of the patient. Conflict of interest.

Je nutno pečlivě a často Pheochromocytoma (PHEO or PCC) is a rare tumor of the adrenal medulla composed of chromaffin cells, also known as pheochromocytes.

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.
