Molecular imaging and therapy have made important contributions to the diagnosis and treatment of many medical disease processes, especially in the area of oncology. The advancements in planar imaging, SPECT/CT, positron emission tomography (PET), PET/CT, PET/MRI and targeted molecular radiotherapy will continue to play an increasing role in patient care as newer molecular agents are introduced into clinical medicine. The open access book Molecular Imaging and Therapy provides a robust introduction into selected clinical topics that utilize molecular imaging and targeted radiotherapy and provides sufficient evidence-based details to allow clinicians of various specialties and backgrounds to gain a thorough understanding of the appropriate clinical uses and benefits of these molecular imaging and therapy techniques. The information in the 12 chapters of this book will greatly benefit Nuclear Medicine Physicians and Radiologists currently in practice and in training but will also be very useful to healthcare providers of all specialties wishing to stay current in their understanding of these molecular techniques as they apply to a wide spectrum of oncological and non-oncological diseases. Each chapter is written by molecular imaging experts in each topic. The authors provide the most clinically relevant and up-to-date research data on each topic and effectively incorporate this information into a format that is easy to comprehend by imaging and non-imaging specialists alike. Molecular Imaging and Therapy is practically organized by disease process, allowing the reader to easily locate an area to gain further knowledge. Whether it is used to explore past contributions or get a look forward to future developments in this field, this book will have very useful information for all.
