This guide comprises up-to-date case-based illustrations on the use of dual tracer molecular imaging, where there is good evidence that patients will benefit from improved disease assessments resulting in altered patient management and outcomes. This book documents the importance of contemporaneous utility of molecular imaging probes utilizing multimodality imaging tools which highlight alterations in cellular changes of various mechanisms that outline common and interesting features of cancer genesis and sequelae of other non-communicable diseases in cardiology and neurology. This book edition also highlights problems and new strategies in diagnosing pediatric diseases utilizing these imaging techniques.
