123I-Metaiodobenzylguanidine Myocardial Scintigraphy in Lewy Body-Related Disorders: A Literature Review
نویسندگان
چکیده
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. (123)I-metaiodobenzylguanidine (MIBG) scintigraphy is a well-known tool to evaluate cardiac sympathetic denervation in the Lewy body-related disorders. MIBG scintigraphy showed low uptake of MIBG in the Lewy body-related disorders, including Parkinson's disease, dementia with Lewy bodies, pure autonomic failure and rapid eye movement sleep behavior disorder. This review summarizes previous results on the diagnostic applications of MIBG scintigraphy in Lewy body-related disorders.

Uptake index of 123I-metaiodobenzylguanidine myocardial scintigraphy for diagnosing Lewy body disease
Objective(s): Iodine-123 metaiodobenzylguanidine (123I-MIBG) myocardial scintigraphy has been used to evaluate cardiac sympathetic denervation in Lewy body disease (LBD), including Parkinson’s disease (PD) and dementia with Lewy bodies (DLB). The heart-tomediastinum ratio (H/M) in PD and DLB is significantly lower than that in Parkinson’s plus syndromes and Alzheimer’s disease. Although this ra...

Objective(s): We recently developed a new uptake index method for 123I-metaiodobenzylguanidine (123I-MIBG) heart uptake measurements by using planar images (radioisotope angiography and planar image) for the diagnosis of Lewy body disease (LBD), including Parkinson’s disease (PD) and dementia with Lewy bodies(DLB). However, the diagnostic accuracy of the uptake index was approximately equal to ...

UNLABELLED The purpose of this study was to investigate myocardial uptake of 123I-metaiodobenzylguanidine (MIBG) in patients with pure autonomic failure (PAF), which has pathologic features in common with idiopathic Parkinson's disease (IPD) and dementia with Lewy bodies (DLB). METHODS Six patients with PAF, 130 with IPD, 21 with DLB, 9 with corticobasal degeneration (CBD), 11 with progressiv...
متن کاملCardiac 123I-metaiodobenzylguanidine Scintigraphy in a Patient with Familial Parkinsonism with Parkin Gene Mutation
A decreased cardiac (123)I-metaiodobenzylguanidine ((123)I-MIBG) uptake has been used as a powerful tool to identify Lewy body disease, such as idiopathic parkinson's disease (IPD). We performed cardiac (123)I-MIBG scintigraphy in patient with autosomal recessive juvenile parkinsonism (ARJP) with parkin gene mutation (PARK2). The findings showed normal cardiac (123)I-MIBG uptake. Therefore, alt...
