Table 1 Comparison of split function computed with Q PET/CT and the recommended methods (anatomic estimation for lobar split function, conventional perfusion scan for lung split function) for all lobes and lungs regardless of index lesion

From: Gallium-68 perfusion positron emission tomography/computed tomography to assess pulmonary function in lung cancer patients undergoing surgery
