Cardiac I-meta-iodobenzylguanidine (MIBG) uptake was measured in 11 patients with dementia with Lewy bodies (DLB), 10 patients with Alzheimer’s disease (AD), and 10 age matched control subjects. The severity of cognitive impairment and duration of symptoms in patients with DLB matched that in the patients with AD. The heart/mediastinum (H/M) ratio of MIBG uptake in the patients with AD was indi...

Radiopharmaceuticals that incorporate radioactive iodine in combination with single-photon emission computed tomography imaging play a key role in nuclear medicine, with applications in drug development and disease diagnosis. Despite this importance, there are relatively few general methods for the incorporation of radioiodine into small molecules. This work reports a rapid air- and moisture-st...

The modalities of uptake and storage of iodine-labeled m-iodobenzylguanidine (MIBG) by four human neuroblastoma cell lines have been studied. SK-N-BE(2)C cell line has been shown to possess the specific (type 1) MIBG uptake, as well as an efficient extravesicular storage mechanism. Conversely, LAN-5 cells, which show a nonsaturation kinetic of MIBG incorporation, lack only the ability to effici...

Myocardial normal databases for stress myocardial perfusion study have been created by the Japanese Society of Nuclear Medicine Working Group. The databases comprised gender-, camera rotation range- and radiopharmaceutical-specific data-sets from multiple institutions, and normal database files were created for installation in common nuclear cardiology software. Based on the electrocardiography...

Pure autonomic failure is challenging as it can be the presenting feature of a central nervous system syncleinopathy such as Parkinson's disease (PD) or multiple system atrophy (MSA). Because the prognosis of MSA and PD is so different, predictive features for a possible conversion can be extremely valuable. In this paper, we report three cases (two with autopsy-proven diagnosis) that had isola...

The importance of neuronal dysfunction in the progression of heart failure and the utility of cardiac sympathetic imaging for identifying ischemic cardiomyopathy patients who are at high risk of sudden cardiac death is well established. On the basis of the results of the ADMIRE-HF (AdreView Myocardial Imaging for Risk Evaluation in Heart Failure) multicenter trial, 123I-meta-iodobenzylguanidine...
