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...
OBJECTIVES The aim of this study was to determine whether left ventricular ejection fraction (LVEF) influences the relationship between abnormal myocardial sympathetic innervation imaging by iodine 123 meta-iodobenzylguanidine ((123)I-mIBG) and outcomes in patients with heart failure (HF). BACKGROUND In systolic HF, both abnormal (123)I-mIBG imaging and reduced LVEF are associated with higher...
BACKGROUND AND PURPOSE Progressive changes in the substantia nigra pars compacta and locus ceruleus of patients with Parkinson disease and Alzheimer disease visualized by neuromelanin MRI and cardiac postganglionic sympathetic nerve function on (123)I-metaiodobenzylguanidine scintigraphy have not been fully evaluated. We compared the diagnostic value of these modalities among patients with earl...
