This atlas explores the latest advances in radionuclide imaging in the field of inflammatory diseases and infections, which now typically includes multimodality fusion imaging (e.g. in SPECT/CT and in PET/CT). In addition to describing the pathophysiologic and molecular mechanisms on which the radionuclide imaging of infection/inflammation is based, the clinical relevance and impact of such procedures are demonstrated in a collection of richly illustrated teaching cases, which describe the most commonly observed scintigraphic patterns, as well as anatomic variants and technical pitfalls. Special emphasis is placed on using tomographic multimodality imaging to increase both the sensitivity and specificity of radionuclide imaging.The aim of the second edition of this book is to update the first (published in 2013) by reflecting the changes in this rapidly evolving field.
