It is refreshing to have a text on emission molecular imaging relevant to animals and human beings with an emphasis on those factors that detract from resolution and quantification. This book implicitly distinguishes between molecular imaging of emitters and molecular imaging provided by magnetic resonance techniques such as magnetic resonance spectroscopy, magnetic resonance imaging of hyperpolarized and other contrast agents, and other magnetic resonance methods wherein the response to the injected pattern of the radiofrequency field is measured. ... In sum, this book shows how researchers have overcome limitations in emission tomography noted 40 years ago and have brought the methods to the goal of high spatial resolution and quantification. Most importantly, these advances have enabled clinically useful applications not available to other diagnostic methods. -From the Foreword by Thomas F. Budinger, University of California, Berkeley, USA "This is a fairly comprehensive survey of current and future applications of emission tomography and associated reconstruction, correction, and image post-processing methods, with an emphasis on quantitative preclinical and clinical molecular imaging research (mostly PET). An advanced book, it is one written primarily from a computational science perspective. This book would benefit most those scientists with at least basic prior knowledge of the underlying physics and applications of, as well as a research interest in, PET, SPECT, and hybrid molecular imaging." -William D Erwin, MS, University of Texas MD Anderson Cancer Center, Houston, USA
