In addition to resting blood pressure and heart rate in a sitting position, the 131 I-MIBG) scintigraphy, adrenal venous sampling and polysomnography. Global MIBG uptake was assessed using the ratio of [(123)I]MIBG uptake in the heart to the upper mediastinum (H/M) on planar scintigraphic data. Regional MIBG uptake was determined on two single photon emission tomography scans in regions of the left ventricle. The mean H/M ratios were significantly different among the three groups (P < 0.0001).

Metaiodobenzylguanidine MIBG MIBG, a catecholamine analog, labelled with I or I, is a Jod-123 Ioflupan (Datscan).

2019-11-04 · Scintigraphic assessment of sympathetic myocardial innervation allows us to evaluate the heart failure prognosis and the effectiveness of interventional treatment. The method is based on use of the radiopharmaceutical 123 I-methiodiobenzylguanidine (123 I-MIBG), which is a structural analogue of norepinephrine and is able to selectively accumulate in the sympathetic nerve endings. In summary, cardiac 123I-MIBG scintigraphy is a highly specific and valuable tool to discriminate Parkinson syndromes and to access postganglionic autonomic (cardiac) impairment. 123I-MIBG analysis delivers important insights in pathophysiological processes and plays a significant role in scientific approaches and in specific clinical diagnostics in the broad spectrum of movement disorders and other diseases and syndromes. I-123 MIBG scintigraphy was performed in 7 patients with congestive heart failure (CHF) of NYHA class I-III (6 with dilated cardiomyopathy and 1 with Adriamycine cardiomyopathy) and in 2 normals. The SPECT and anterior planar myocardial images were obtained 15 minutes after (initial images) and 4 hours after (delayed images) an injection of I-123 MIBG (111 MBq). In clinical practice, the MIBG scintigraphy is mainly used to detect (and sometimes to treat) neuroendocrine tumours, primarily pheochromocytomas and neuroblastomas [3–8].

MIBG scan is a scintigraphic study that uses metaiodobenzylguanidine, norepinephrine analog, labeled to iodine-123 or iodine-131. It is indicated in the investigation of pheochromocytoma. MIBG is positive in: neuroblastoma olfactory neuroblast The sympathetic innervation of the heart was measured by I-123-MIBG-Scintigraphy. Therefore on the one hand the global I-123-MIBG uptake (HMQ; heart/mediastinum activity ratio) and on the other hand segmental I-123-MIBG uptake was measured. 4 patients could be reevaluated 57.5±8.6 days after coronary artery bypass by the same procedure.

In some cases, it is difficult to differentiate essential tremor (ET) from Parkinson's disease (PD), especially in the early stages of the disease. We investigated cardiac sympathetic dysfunction using 123 I‐metaiodobenzylguanidine (MIBG) myocardial scintigraphy in 22 patients with ET, in comparison with early PD and tremor‐dominant PD (TDPD). Scintillography is an imaging method of nuclear events provoked by collisions or charged current interactions among nuclear particles or ionizing radiation and atoms which result in a brief, localised pulse of electromagnetic radiation, usually in the visible light range (Cherenkov radiation). information about mIBG scintigraphy in cancer patients. The guidelines describe the mIBG scintigraphy protocol currently used in clinical routine, but do not include all existing procedures for neuroendocrine tumours.

However, the lack of consensus on how to extrapolate the available mIBG data into clinical practice is reﬂ ected in the absence of mIBG in the majority of current guidelines regarding heart failure except in Japan.

Renal K/M ratios and WR values were obtained for the right and left kidneys. MIBG serves as a whole-body, non-invasive scintigraphic screening for germ-line, somatic, benign, and malignant neoplasms originating from the adrenal glands. It is able to detect both intra and extra-adrenal disease. The imaging is highly sensitive and specific. Neuroimaging markers for Parkinson's disease (PD)/dementia with Lewy bodies (DLB) include dopamine transporter (DAT) scanning and metaiodobenzylguanidine (MIBG) myocardial scintigraphy.
