Dynamic perfusion digital radiography for predicting pulmonary function after lung cancer resection

Abstract Background Accurate prediction of postoperative pulmonary function is important for ensuring the safety patients undergoing radical resection lung cancer. Dynamic perfusion digital radiography an excellent and easy imaging method detecting blood flow in compared with less-convenient conventional scintigraphy. As such, present study aimed to confirm whether dynamic can be evaluated comparison scintigraphy predicting early complications. Methods spirometry were performed before 1 3 months after Correlation coefficients between ratios calculated using then confirmed same cases. In all who underwent radiography, correlation predicted values from ratio, measured examined. Furthermore, ppo%FEV1 or ppo%DLco values, which indicated risk perioperative complications, Results A total 52 participants satisfied inclusion criteria analyzed. Blood showed acceptable predictive accuracy. FEV1 obtained actual similar. All those spirometry. significant difference was observed respiratory complications but not cardiovascular Conclusions Our demonstrated that a suitable alternative given its ability it seemed modality because advantages, such as simplicity, low cost, ease obtaining in-depth functional information.
