Quantification in emission tomography : Challenges , solutions , and performance

  title={Quantification in emission tomography : Challenges , solutions , and performance},
  author={Ir{\`e}ne Buvat},
Emission tomography (single photon emission tomography—SPECT—and positron emission tomography—PET) offers a great potential for the quantitative characterization of functional and molecular processes in vivo. Indeed, voxel values in the reconstructed SPECT and PET images can theoretically be translated into a well-understood physical quantity, namely radiotracer concentration, from which all kinds of parameters characterizing molecular processes can be derived using appropriate modeling.
