Letter to the Editor: Interobserver Variability of Heart-to-Mediastinum Ratio in I-123 MIBG Sympathetic Imaging
One of the significant contributors to the variation of H/ M ratio in cardiac imaging, are the settings of the regions of interest (ROIs) that are used. Currently, as correctly described by Chen et al. [1, 2], there are three main approaches ROI is placed along the anterior part of the LV wall [2]. In our current ongoing study in pediatric patients by van der Palen et al.., we compared both app...
متن کاملCardiac sympathetic imaging with mIBG in heart failure.
Cardiac sympathetic imaging with meta-iodobenzylguanidine (mIBG) is a noninvasive tool to risk stratify patients with heart failure (HF). In patients with ischemic and nonischemic cardiomyopathy, cardiac mIBG activity is a very powerful predictor of survival. Cardiac sympathetic imaging can help in understanding how sympathetic overactivity exerts its deleterious actions, which may result in be...
متن کاملCorrection of collimator-dependent differences in the heart-to-mediastinum ratio in 123I-metaiodobenzylguanidine cardiac sympathetic imaging: Determination of conversion equations using point-source imaging
BACKGROUND Septal penetration causes collimator-dependent differences in the heart-to-mediastinum (H/M) ratio in 123I-metaiodobenzylguanidine (MIBG) cardiac imaging. We investigated generally applicable methods to correct such differences. METHODS AND RESULTS Four hours after 123I-MIBG injection, 40 patients underwent anterior chest imaging successively with medium-energy (ME) and various non...
متن کاملInfluence of ejection fraction on the prognostic value of sympathetic innervation imaging with iodine-123 MIBG in heart failure.
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...
متن کاملCardiac sympathetic imaging with mIBG in cirrhosis and portal hypertension: relation to autonomic and cardiac function.
Autonomic and cardiac dysfunction is frequent in cirrhosis and includes increased sympathetic nervous activity, impaired heart rate variability (HRV), and baroreflex sensitivity (BRS). Quantified (123)I-metaiodobenzylguanidine (mIBG) scintigraphy reflects cardiac noradrenaline uptake, and in patients with cardiac failure it predicts outcome. In this study, we aimed to investigate cardiac sympat...
