CUDC-907, a dual PI3K/histone deacetylase inhibitor, increases meta-iodobenzylguanidine uptake (123/131I-mIBG) in vitro and in vivo: a promising candidate for advancing theranostics in neuroendocrine tumors

Journal of Translational Medicine, 2023
Background Neuroblastoma (NB) and pheochromocytoma/paraganglioma (PHEO/PGL) are neuroendocrine tumors. Imaging of these neoplasms is performed by scintigraphy after injection of radiolabeled meta-iodobenzylguanidine (mIBG), a norepinephrine analog taken ...

Neuroblastoma Perinatal – Um Desafio para o Neonatologista [PDF]

, 2015
O neuroblastoma é o tumor maligno mais frequente no período neonatal. O diagnóstico pré-natal tem aumentado devido à qualidade da ecografia obstétrica, que permite a deteção de formações de pequenas dimensões nas glândulas suprarrenais.

Cardiac 123I-MIBG scintigraphy in patients with drug induced parkinsonism [PDF]

Journal of Neurology, Neurosurgery & Psychiatry, 2005
Cardiac sympathetic dysfunction was investigated using 123I-metaiodobenzylguanidine (MIBG) myocardial scintigraphy in 20 patients with drug induced parkinsonism (DIP). The mean heart to mediastinum ratio was significantly greater in patients with DIP than in those with Parkinson's disease (mean (SD): 2.07 (0.39) v 1.28 (0.15 ...

Efeito do carvedilol a curto prazo na atividade simpática cardíaca pela cintilografia com 123I-MIBG Effects of short-term carvedilol on the cardiac sympathetic activity assessed by 123I-MIBG scintigraphy

Arquivos Brasileiros de Cardiologia, 2010
FUNDAMENTO: Alterações autonômicas na insuficiência cardíaca estão associadas a um aumento da morbimortalidade. Vários métodos não invasivos têm sido empregados para avaliar a função simpática, incluindo a imagem cardíaca com 123I-MIBG. OBJETIVO: Avaliar

Cardiac MIBG Scintigraphy in Neurodegenerative Parkinsonism: Limitations in Clinical Practice

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Reduced cardiac uptake on 123Iodine‐metaiodobenzylguanidine (MIBG) scintigraphy is a valuable tool for differentiating neurodegenerative parkinsonism but interpretation can be difficult due to comorbidities and drug‐tracer interactions.

I-Metaiodobenzylguanidine Myocardial Scintigraphy in Lewy Body-Related Disorders: A Literature Review [PDF]

Journal of Movement Disorders, 2015
Lewy body-related disorders are characterized by the presence of Lewy bodies and Lewy neurites, which have abnormal aggregations of α-synuclein in the nigral and extranigral areas, including in the heart.

The importance of longitudinal evaluation using DAT‐SPECT in organophosphate‐induced toxic parkinsonism

Psychiatry and Clinical Neurosciences Reports, Volume 5, Issue 2, June 2026.
We performed longitudinal evaluation using magnetic resonance imaging (MRI) and dopamine transporter single‐photon emission computed tomography (DAT‐SPECT) in a case of organophosphate‐induced toxic parkinsonism. Fluid‐attenuated inversion recovery (FLAIR) images showed bilateral striatal hyperintensity in the acute phase, followed by reduction of ...

Imaging of High‐Risk Neuroblastoma: Recommendations From SIOPEN Radiology and Nuclear Medicine Specialty Committees

Pediatric Blood &Cancer, Volume 73, Issue 5, May 2026.
ABSTRACT Neuroblastoma is the most common extracranial solid tumor in early childhood. Its clinical behavior is highly variable, ranging from spontaneous regression to fatal outcome despite intensive treatment. The International Society of Pediatric Oncology Europe Neuroblastoma Group (SIOPEN) Radiology and Nuclear Medicine Specialty Committees ...
