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...
UNLABELLED Accelerated cardiac washout of (123)I-metaiodobenzylguanidine (MIBG), which is clinically used as an index of cardiac neuropathy in diabetes, is ascribed to decreased norepinephrine reuptake into synaptic vesicles. However, accelerated washout frequently contrasts with preserved early tracer uptake, whose significance remains undetermined. The aim of this study was to investigate in ...
UNLABELLED Myocardial imaging with 123I-metaiodobenzylguanidine (MIBG) was performed on 35 patients with Parkinson's disease and 24 control subjects to evaluate cardiac sympathetic function in patients with Parkinson's disease, verify this phenomenon and examine whether myocardial MIBG uptake and clearance are correlated with the clinical severity of Parkinson's disease. METHODS We studied 35...
AIM To assess the spatial relation between regional cardiac sympathetic innervation and regional ventricular repolarisation indicated by ventricular wall motion abnormality in patients with congenital long QT syndrome. DESIGN Regional percentage uptake and washout rate of (123)I metaiodobenzylguanidine (MIBG) were measured to assess cardiac sympathetic innervation in septum, anterior wall, la...
BACKGROUND AND PURPOSE (123)I cardiac meta-iodobenzylguanidine (MIBG), an analogue of norepinephrine, has been used to estimate myocardial sympathetic nerve function. We investigate whether cardiac-MIBG SPECT is clinically applicable in the differentiation of Parkinson's disease (PD) from parkinsonian syndromes. METHODS Cardiac-MIBG scintigraphy was performed in 27 controls, in 40 patients wi...
Iodine-123-MIBG (123I-MIBG) scintigraphy were performed for 23 patients with neuroblastoma at diagnosis. The intensity of MIBG activity in the primary tumor was evaluated visually (grade 3; intense uptake-grade 0; no definite uptake), and its relationship to the size, degree of tumor spread, urinary catecholamine metabolites (VMA, HVA), and histological types were investigated. The results of 1...
OBJECTIVES We investigated the relationship between iodine-123-metaiodobenzylguanidine (123I-MIBG) findings and myocardial contractile reserve in patients with mild to moderate dilated cardiomyopathy (DCM). BACKGROUND Little is known regarding the relationship between cardiac sympathetic nervous function and myocardial contractile reserve in DCM. METHODS Twenty-four DCM patients who showed ...
BACKGROUND Chemotherapy with anthracyclines and trastuzumab can cause cardiotoxicity. Alteration of cardiac adrenergic function assessed by metaiodobenzylguanidine labeled with iodine-123 (123I-mIBG) seems to precede the drop in left ventricular ejection fraction. OBJECTIVE To evaluate and to compare the presence of cardiovascular abnormalities among patients with breast cancer undergoing che...
