MIBG myocardial scintigraphy in progressive supranuclear palsy Unlike in PD, PSP patients exhibited a mild decrease in MIBG accumulation in MIBG myocardial scintigraphy, which may be related to brainstem atrophy. 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. Cardiac 123I-metaiodobenzylguanidine (123I-MIBG) scintigraphy is used to discriminate PD and MSA by means of cardiac postganglionic autonomic involvement (4 – 6). Cardiac uptake of the synthetic norepinephrine analog (123I-MIBG) depends on integrity of postganglionic sympathetic neurons. MIBG uptake was determined by calculating the heart-to-mediastinum-uptake ratio (H/M). RESULTS: The average H/M ratio was 1.42 ± 0.35.

Scholte, Arnold F. Jacobson, Hein J. Verberne, For what endpoint does myocardial 123 I-MIBG scintigraphy have the greatest prognostic value in patients with chronic heart failure? Background Different studies have found diminished cardiac metaiodobenzylguanidine (MIBG) uptake in Lewy body (LB) related conditions (Parkinson’s disease (PD) and Lewy body dementia (LBD)). However, delayed heart/mediastinum (d-H/M) ratio diagnostic cutoff points are debated in parkinsonian syndromes. Methods We performed a monocentric retrospective analysis on 62 consecutive parkinsonian scintigraphy, CAN by HRV and 123I-mIBG myocardial scintigraphy were performed. Two or more abnormal tests were defined as CAN-positive (ECG-based CAN) and one or fewer as CAN-negative. CAN assessed by 123I-mIBG scintigraphy was defined as abnormal if the heart-to-mediastinum ratio was <1.8, the washout rate was >25%, or the total defect score Made available by U.S. Department of Energy Office of Scientific and Technical Information Relationship Between the Occurrence of Adverse Cardiac Event and 123I-mIBG Uptake on Planar Scintigraphy Categorized as High or Low Heart to Mediastinum (H/M) Ratio [ Time Frame: Approximately 24 months from the date of administration of 123I-mIBG ] 123I-MIBG scintigraphy was developed to evaluate cardiac sympathetic nervous function, and the usefulness of 123I-MIBG imaging has been demonstrated in many cardiac diseases (20–24).

Currently, 123 I-MIBG Cardiac sympathetic hyperactivity is related to fatal arrhythmias and can be non-invasively assessed with 123I-meta-iodobenzylguanide (123I-mIBG) scintigraphy. We conclude that cardiac sympathetic activity assessed with 123I-mIBG scintigraphy is a promising tool to better identify patients who will benefit from ICD implantation. 2020-07-01 · Renal 123 I-MIBG scintigraphy was performed simultaneously with cardiac scintigraphy.

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].

However, Although several promising results have been published that suggest the usefulness of MIBG cardiac scintigraphy for differentiation of DLB and AD, most of these studies were conducted under very strict exclusion criteria because abnormal cardiac MIBG uptake has been reported in patients with diabetes mellitus, thyroid diseases, heart failure, and ischemic heart disease. 123 I-MIBG has clear advantages over 131 I-MIBG in terms of diagnostic imaging, which has made it the agent of choice for scintigraphy of pediatric neuroblastoma. The 123 I label has a principal photon energy of 159 keV, which is much more suited for imaging with conventional gamma cameras ( 27 ).
