Progress in clinical development of magnetic resonance imaging (MRI) substrate-sensors of enzymatic activity has been slow partly due to the lack of human efficacy data. We report here a strategy that may serve as a shortcut from bench to bedside. We tested ultra high-resolution 7T MRI (µMRI) of human surgical histology sections in a 3-year IRB approved, HIPAA compliant study of surgically clipped brain aneurysms. µMRI was used for assessing the efficacy of MRI substrate-sensors that detect myeloperoxidase activity in inflammation...

INTRODUCTION: Burn care requires multiple disciplines to collaborate to achieve best patient care. Because of this, rounds involve a very large burn team to assess patients' wounds and formulate plans. To decrease the amount of team members on rounds, our burn center implemented a new budding technology: telemedicine. We created "Zoom Rounds," a Health Insurance Portability and Accountability Act (HIPAA)-compliant, secure videoconferencing system to relay patient wound evaluations to a remote conference room where team members can participate digitally...
