Complication and Lung Function Impairment Prediction Using Perfusion and CT Air Trapping

"The novel predictive data in this study includes 5 predefined variables derived from thoracic CT scans:~(i) Expiratory to inspiratory ratio of mean lung density (MLDe/i), total; (ii) MLDe/i of the section to be excised / MLDe/i total; (iii) Percentage of emphysema according to voxel thresholding at -950 HU (PVOX-950), total; (iv) PVOX-950 for the section to be excised; (v) Iodine concentration \[I\] of the section to be excised / \[I\] total."

Surgical resection will be characterised by type (pneumonectomy, bi-lobectomy, lobectomy, or lobectomy with anastomosis resection), whether or not lymph node dissection was performed, and whether or not the resection was atypical.
