A study in the Journal of Nuclear Medicine revealed that FDG PET could measure pulmonary blood flow in acute lung injury. French researchers evaluated swine with acute lung injury and control animals with FDG PET. "The main findings of the present study were that assessment of [regional blood fraction] by compartmental modeling of F-18 FDG kinetics provides an unbiased and precise estimation of PBF," the authors wrote, noting the approach is applicable to healthy and injured animals over many tidal volumes and positive end-expiratory pressures. "Taken together, these findings encourage the use of this technique to assess PBF when F-18 FDG PET is performed," they wrote.
