Abstract OBJECTIVES We compared the usefulness of single-photon emission computed tomography/computed tomography (SPECT/CT) and lung perfusion scintigraphy (LPS) for predicting postoperative lung function by comparing patients with borderline lung function. METHODS A total of 274 patients who underwent simultaneous LPS and SPECT/CT and had a forced expiratory volume in 1 s (FEV1) or diffusing capacity for carbon monoxide (DLCO) under 80% were included. The % uptake by LPS was calculated by the posterior-oblique method. The concordance and difference of the % uptake, predicted postoperative (ppo) FEV1 and ppoDLCO as determined by 2 methods were evaluated. The association between ppo values and actual postoperative FEV1 and DLCO was examined. Subgroup analysis was conducted in redo-operation cases. RESULTS The % uptake of each lobe, except the right middle lobe, showed fair concordance (concordance correlation coefficients for right upper, middle, lower, left upper and lower lobe = 0.61, 0.37, 0.71, 0.66 and 0.69, respectively). ppoFEV1 and ppoDLCO also revealed high concordance between both methods (concordance correlation coefficient = 0.93 for ppoFEV1 and concordance correlation coefficient = 0.92 for ppoDLCO) without a significant difference (P = 0.42 for ppoFEV1; P = 0.31 for ppoDLCO). Both ppoFEV1 and ppoDLCO showed a significantly high correlation with the actual FEV1 (r = 0.77, P < 0.01 for LPS, r = 0.77, P < 0.01 for SPECT/CT) and DLCO (r = 0.62, P < 0.01 for LPS, r = 0.62, P < 0.01 for SPECT/CT). High concordance of % uptake, ppoFEV1 and ppoDLCO was present in redo-operation patients. CONCLUSIONS Both LPS and SPECT/CT showed high predictability for actual postoperative lung function, and LPS showed good performance to estimate ppoFEV1 and ppoDLCO with reference to SPECT/CT, even in redo-operation cases.

Background Predicting postoperative lung function is critical in lung cancer patients. Perfusion scintigraphy has been used to estimate postoperative function after lung resection. Purpose To evaluate the usefulness of the posterior oblique method in relation to other conventional processing methods for predicting postoperative lung function using lung perfusion scintigraphy. Material and Methods Fifty-five patients with non-small-cell lung cancer who underwent lobectomy were enrolled. Forced expiratory volume in 1 s (FEV1) values were obtained from preoperative and postoperative pulmonary function tests. After performing lung perfusion scintigraphy, predicted FEV1 values were calculated using the segment, conventional, posterior, and posterior oblique methods. Postoperative FEV1 values were compared with predicted FEV1 values. Results The mean value of the preoperative FEV1 was 2.29 L and that of the postoperative FEV1 was 1.89 L. The mean values of the predicted postoperative FEV1 values for the segment, conventional, posterior, and posterior oblique were 1.83 L, 1.94 L, 1.88 L, and 1.89 L, respectively. Between the observed and predicted FEV1 values, there was a strong correlation without significant difference except for conventional method. Bland–Altman analysis showed that segment and posterior methods underestimated the FEV1, whereas conventional and posterior oblique methods overestimated the FEV1. Conclusion Predictions with each processing method of lung perfusion scintigraphy showed nearly similar results to the actual postoperative lung function. The posterior oblique method of lung perfusion scintigraphy showed a very small difference to such an extent as to be equal to the observed FEV1, implying that this method may be applied for predicting postoperative lung function in lung cancer patients.
