Combinación de realce tardío de gadolinio en cardiorresonancia y actividad adrenérgica con 123I-MIBG en la estratificación pronóstica en pacientes co…

INTRODUCCIÓN: la insuficiencia cardíaca (IC) tiene elevadas prevalencia e incidencia, así como morbilidad y mortalidad. Actualmente, la IC se ha convertido en un problema de salud pública y la mayoría de las muertes son debidas a causas cardiovasculares, principalmente muerte súbita cardíaca (MSC). La fracción de eyección (FEVI) es un importante predictor de eventos cardiovasculares en pacientes con disfunción sistólica de ventrículo izquierdo (VI). Los datos europeos más recientes (estudio ESC-HF long term) demuestran que las tasas de mortalidad por causa cardíaca son mayores en pacientes con IC con FEVI reducida que con FEVI conservada. Y en pacientes con IC la mayoría de las muertes son …
Dual Diagnostic Role of 123I-MIBG Scintigraphy in Inverted-Takotsubo Pattern Cardiomyopathy
2015
We highlight the dual role of I-MIBG scintigraphy in inverted-Takotsubo pattern cardiomyopathy, the diagnosis of which is sometimes challenging: Firstly, I-MIBG scintigraphy can show myocardial sympathetic dysfunction (low I-MIBG uptake) in the hypokinetic basal segments, sparing the left ventricle apex. It is helpful in the imaging diagnosis of inverted-Takotsubo pattern cardiomyopathy and confirms that acute dysfunction of myocardial sympathetic nerve endings occurs with this cardiomyopathy. Secondly, I-MIBG scintigraphy is an accurate imaging examination to detect and localize pheochromocytoma; it can help in the search for an endogenous cause of this adrenergic stress-related cardiomyop…
Noradrenergic innervation of the pineal gland — histochemical basis of scintigraphic imaging?
1987
There is first evidence that the adult human pineal gland may be equipped with noradrenergic fibers as is the case in a variety of mammalian species. It therefore appears worthwhile to investigate the capacity of pineal noradrenergic nerves to take up 123I-MIBG, a prerequisite for scintigraphic imaging.

SEMIQUANTITATIVE 123I-METAIODOBENZYLGUANIDINE SCORE AS A PROGNOSIS MARKER IN HIGH RISK NEUROBLASTOMA: CORRELATION WITH OTHER PROGNOSTIC MARKERS AND MINIMAL RESIDUAL DISEASE IN BONE MARROW. Purpose: Metaiodobenzylguanidine (MIBG), specifically taken up in cells of sympathetic origin, provides a highly sensitive and specific marker for the detection of metastases in neuroblastoma. Our aim has been to investigate whether response to induction therapy, evaluated by 123I-MIBG correlates with overall survival (OS) and other prognostic factors in children with metastatic neuroblastoma. Patients and Methods: Medical records and imaging studies from 28 patients with stage 4 neuroblastoma have been r…
[177Lu]Lu-DOTA-TATE and [131I]MIBG Phenotypic Imaging-Based Therapy in Metastatic/Inoperable Pheochromocytomas and Paragangliomas: Comparative Result…
2022
PurposeThe aim of the study is to assess phenotypic imaging patterns and the response to treatment with [177Lu]Lu-DOTA-TATE and/or [131I]MIBG in paragangliomas (PGLs) and pheochromocytomas (PHEOs), globally and according to the primary location.MethodsThis is a 17-patient retrospective observational study, with 9 cases treated with [177Lu]Lu-DOTA-TATE and 8 with [131I]MIBG (37 total treatments). Functional imaging scans and treatment responses were studied in order to choose the best therapeutic option and to define the progression-free survival (PFS) and disease control rate (DCR) according to treatment modality and primary location.ResultsAll patients were studied with phenotypic nuclear …
