BACKGROUND Cardiac 123I-meta-iodobenzylguanidine (MIBG) uptake is quantified using the heart-to-mediastinum ratio (HMR) with an Anger camera. The relationship between HMR determined using D-SPECT with a cadmium-zinc-telluride detector and an Anger camera is not fully understood. Therefore, the present study aimed to define this relationship using images derived from a phantom and from patients....
Cardiac autonomic dysfunction plays a pivotal role in the pathogenesis of heart failure with reduced left ventricular ejection fraction. Angiotensin II and α1-adrenergic receptor agonist also induce myocardial hypertrophy and diastolic dysfunction in animal models [5]. The role of sympathetic dysfunction in the pathophysiology of diastolic dysfunction without heart failure among subjects treate...
Radiolabelled metaiodobenzylguanidine (MIBG), a monoamine uptake and storage tracer, is used for the scintigraphic detection of tumors deriving from the neural crest [1,2] as well as for assessing the functional status of the sympathetic nerve endings in the human heart and lungs [3, 4]. While there have been several publications dealing with the clinical applications of this tracer, less is kn...
Background: Iodine-123 metaiodobenzylguanidine (123I-MIBG) myocardial scintigraphy has been accepted as one of the most useful methods for the diagnosis of Parkinson’s disease (PD). Moreover, the accumulated evidence has indicated that the heart-to-mediastinum (H/M) ratio correlates with the disease severity of hypokinesia/ bradykinesia and rigidity. The present report describes the wearing-off...
