UNLABELLED Chronic renal failure (CRF) patients on dialysis frequently show reduced heart rate variability (HRV), which has been reported to be corrected by renal transplantation. Recently, (123)I-metaiodobenzylguanidine ((123)I-MIBG) scintigraphy has been used to evaluate cardiac sympathetic innervation, and uremic patients often show marked abnormalities of cardiac (123)I-MIBG uptake. We inve...
UNLABELLED We compared functional imaging modalities including PET with 6-(18)F-fluorodopamine ((18)F-DA) with (123)I-metaiodobenzylguanidine ((123)I-MIBG) and somatostatin receptor scintigraphy (SRS) with (111)In-pentetreotide in nonmetastatic and metastatic pheochromocytoma (PHEO). METHODS We studied 25 men and 28 women (mean age +/- SD, 44.2 +/- 14.2 y) with biochemically proven nonmetasta...
The aim of this study was to explore if estimates of renal function could explain variability of (123)I-metaiodobenzylguanidine ((123)I-MIBG) assessed myocardial sympathetic activity. Furthermore estimates of renal function were compared to (123)I-MIBG as predictors of cardiac death in chronic heart failure (CHF). Semi-quantitative parameters of (123)I-MIBG myocardial uptake and washout were ca...
UNLABELLED The aim of this study was to evaluate impaired lung uptake of (123)I-metaiodobenzylguanidine ((123)I-MIBG) on SPECT, compared with perfusion SPECT and morphologic CT, in patients with pulmonary emphysema (PE). METHODS (123)I-MIBG SPECT was performed at 15 min and 4 h after intravenous injection of (123)I-MIBG in 36 PE patients with a history of smoking and variable-extent low-atten...
