Assessment of global cardiac I-123 MIBG uptake and washout using volumetric quantification of SPECT acquisitions
BACKGROUND Assessment of cardiac innervation using single-photon emission computer tomography (SPECT) is less established than planar imaging, but may be more suitable for quantification. Therefore, a volumetric quantification of I-123 MIBG SPECT acquisitions was performed. Reproducibility, the effects of extra cardiac I-123 MIBG uptake and the relation with conventional planar indices were eva...
متن کامل[Iodine-123-MIBG scintigraphy in neuroblastoma; relationship between the intensity of uptake and tumor characteristics].
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...

(I-MIBG) Imaging in Brugada Syndrome To the Editor: We read with interest a recent article in Circulation by Wichter et al1 on cardiac autonomic dysfunction in Brugada syndrome. The authors demonstrated that regionally reduced iodine-123-metaiodobenzylguanidine (I-MIBG) uptake in the inferior and septal left ventricular wall was present in 8 (47%) of 17 patients with Brugada syndrome but in non...

متن کاملScatter correction by two-window method standardizes cardiac I-123 MIBG uptake in various gamma camera systems.
UNLABELLED Heart to mediastinum count ratio (H/M) has been commonly utilized as an indicator of myocardial I-123 MIBG uptake. However, normal ranges of H/M were markedly different among various gamma camera systems. The purpose of this study was to clarify whether scatter correction by two-window method standardizes H/M among various gamma camera systems. METHODS Scatter uncorrected and corre...
