Internal dosimetry study of [⁸²Rb]Cl using a long axial field-of-view PET/CT. [PDF]

Eur J Nucl Med Mol Imaging
PURPOSE Long axial field-of-view (LAFOV) positron emission tomography (PET) systems allow to image all major organs with one bed position, which is particularly useful for acquiring whole-body dynamic data using short-lived radioisotopes like 82Rb.
