MIBG Activity in the Gallbladder
Clinical Nuclear Medicine, 2016Whole-body I-MIBG images were acquired in a 12-year-old girl who had metastatic malignant paraganglioma to assess the extent of the metastases. Image quality was suboptimal because of diffusely increased muscle activity, which was related to the labetalol the patient took to control her blood pressure.

Radiolabelled metaiodobenzylguanidine (MIBG) localizes in adrenergic neurons. A study was carried out to evaluate the uptake of this radiopharmaceutical in cerebral tissues. Twenty-three patients with neural crest tumours, who had no evidence of central nervous system disease, were evaluated.

1-23I-MIBG thyroid uptake: Implications for MIBG imaging of the heart
Journal of Nuclear Cardiology, 2016123I-MIBG has been widely used in patients with heart failure and neurological disorders. The patients are pre-treated with Lugol's oral solution or potassium perchlorate to prevent thyroid uptake of unlabeled 123I to limit the thyroid radiation exposure. However, despite the inhibition of the iodide pump, the thyroid is frequently visualized.

Pulmonary metastases from malignant pheochromocytoma were seen with I-123 MIBG SPECT in a 16-year-old girl but were not visualized with I-123 MIBG planar imaging. She had a left adrenalectomy for a pheochromocytoma 7 years earlier. Two small pulmonary nodules were seen on chest X-ray and CT scans.

Quantitative I-123 mIBG SPECT in differentiating abnormal and normal mIBG myocardial uptake
Journal of Nuclear Cardiology, 2012The purpose of this study was to evaluate global quantitation of cardiac uptake on I-123 mIBG SPECT.The study included a pilot group of 67 subjects and a validation group of 1,051 subjects. SPECT images were reconstructed by filtered backprojection, ordered subsets expectation maximization, and deconvolution of septal penetration, respectively.

Uptake of radiopharmaceuticals in the adrenal medulla was first demonstrated in 1967, using C-14-labeled epinephrine and precursors (Morales et al. 1967). In subsequent years this tracer was shown to depict neuroblastomas and pheochromocytomas (Lieberman et al. 1969; Anderson et al. 1973).

Enhancement of 131I-MIBG uptake in carcinoid tumours by administration of unlabelled MIBG
Nuclear Medicine Communications, 2000Iodine-131 metaiodobenzylguanidine (131I-MIBG) has been used with success for the palliation of symptomatic, metastatic carcinoid tumours. However, only 70% of cases are MIBG-avid and tumour uptake is not always sufficient for therapy. At The Netherlands Cancer Institute 34 carcinoid patients with no or insufficient uptake were treated with escalating ...

Metaiodobenzylguanidine (MIBG) is an analog of guanethidine which has been used for imaging a variety of neuroendocrine tumors (NETs). While 131I-MIBG is approved by the FDA for imaging, no reagents are yet approved for therapy. Thus, 131I-MIBG used for therapy trials is either made in accordance with USP regulations or used under an investigational ...

The sympathetic nervous system plays an important role in cardiovascular physiology. Planar MIBG with or without SPECT can be used to visualize the sympathetic innervation of the heart and the abnormalities in innervation caused by, for example, ischemia, heart failure, and arrhythmogenic disorders.
