As functional imaging continues to become increasingly important to everyday clinical practice, clinicians need to know more about the quantitative aspects of physiology and pathophysiology. In straightforward language for the clinician, this book integrates the principles and mathematics of measurement with the physiological systems to which the quantitative problems are applied. Although there is an emphasis on the clinical measurement of radionuclides and quantitative procedures in nuclear medicine, this book has been written with all clinicians in mind. Starting from basic mathematics, the book covers the measurement of blood flow, the peripheral circulation and microvascular solute transfer, the pharmacokinetics of agenda routinely used in nuclear medicine as well as scintillation detectors, data processing and quantification. In separate chapters measurement in the heart, lung, gastro-intestinal tract, liver, spleen, genitourinary tract and the brain are discussed. As imaging has become more functional over the last few years, all clinicians are increasingly using these physiological techniques and so this book should be valuable in the libraries of a wide variety of specialt
