This is a Phase 2 study evaluating the positron-emitting radiopharmaceutical 18F-mFBG as an imaging agent for quantification of myocardial sympathetic innervation. The study will examine a group of stable patients with heart failure (HF) from ischemic cardiomyopathy. All subjects will have left ventricular ejection fraction (LVEF) ≤35% and implantable cardioverter-defibrillators (ICD). The primary objectives of the study will be to:
* document the degree to which 18F-mFBG uptake in the heart is reduced (compared to historical controls)
* characterize the distribution of regional abnormalities in relation to findings on rest/stress positron-emission tomography (PET) myocardial perfusion imaging (MPI)
* determine if there are global and/or regional differences in myocardial sympathetic innervation between subjects who have and have not experienced an appropriate ICD activation within the previous 12 months Effectiveness of 18F-mFBG will be judged in relation to historical experience with other nuclear imaging agents for cardiac sympathetic innervation imaging such as a 123I-meta-iodobenzylguanidine (mIBG) and 11C-hydroxyephedrine (HED).
Safety data will be collected to identify adverse events [AEs] and serious adverse events [SAEs] and characterize the safety profile of 18F-mFBG.

This is a prospective Phase 2 study being performed to document the relationship between 18F-mIBG positron emission tomography (PET) findings in subjects, and expression of the norepinephrine transporter. In addition to collecting safety data for the imaging agent, the study aims to:
* compare the findings against other catacholamine transporters
* evaluate the imaging results at different time points and in different organs
* assess the quality of images with lower doses
* compare the ability to detect neuroblastoma lesions against other imaging agents, and in other tumors

This is a Phase 3 study evaluating the positron-emitting radiopharmaceutical 18F-mFBG as an imaging agent for confirming or excluding the presence of neuroblastoma
