First positronium lifetime imaging with scandium-44 on a long axial field-of-view PET/CT
Despite the favorable physical properties of <sup>44</sup>Sc, the count statistics of three-photon events remains a challenge. The high prompt-photon energy causes a significant amount of random three-photon coincidences with the given methodology and, therefore, increases the statistical uncertainties on the measured oPs lifetime.
