Brief Title: Lutonix AV PAS

Brief Summary: This prospective, global, multicenter, single arm post-approval study is designed to investigate the clinical use and safety of the Lutonix® 035 AV Drug Coated Balloon (DCB) PTA Catheter in subjects presenting with clinical and hemodynamic abnormalities in native arteriovenous (AV) fistulae located in the upper extremity.

Title: MRI Evaluation of Aging Related Changes to the Brain

Brief Title: MRI Evaluation of Aging Related Changes to the Brain

Brief Summary: The purpose of this study is to develop new magnetic resonance imaging (MRI) techniques that can be used to clinically evaluate patients across a spectrum of ages 18+. This study will test magnetic resonance techniques on FDA approved MRI machines. Newly developed MRI sequences will be validated on normal subject brains and compared to standard techniques. This study will evaluate different brain imaging techniques including Arterial Spin Labeling (ASL) perfusion and Inhomogeneous Magnetization Transfer (ihMT) imaging.
