This book is designed as a reference manual that is exceptional in systematically discussing every aspect of nuclear medicine imaging of infections, with careful explanation of the most up-to-date concepts and recent guidelines on diagnostic flowcharts as shared between the EANM, ESR, ESNR, ESCMID, ESC, EACVI, ECCO, ESGAR and EBJIS. It is truly comprehensive, describing all methods, all acquisition parameters, and all interpretation criteria in all infectious diseases. The early chapters discuss currently available radiopharmaceuticals and nuclear medicine imaging technologies, including the hybrid modalities SPECT/CT, PET/CT, and PET/MRI. The remainder of the book is devoted to the nuclear medicine imaging of infections at different body sites as well as fever of unknown origin, fungal infections, and tuberculosis and AIDS-associated infections. Infections represent a real emergency globally, and early diagnosis and treatment follow-up will continue to pose huge challenges. In thiscontext, Nuclear Medicine in Infectious Diseases will be a superb asset for nuclear medicine and infectious disease specialists and other clinicians everywhere.
