To evaluate the correlation between pre-surgical 4-Dimensional Computed Tomography-ventilation (4DCT-ventilation) imaging and post-surgical lung function. To determine whether 4DCT-ventilation is a better predictor of post-surgical lung function than nuclear medicine imaging using pulmonary function tests (PFTs). To determine whether 4DCT-ventilation is a better predictor of post-surgical lung function than nuclear medicine imaging using quality of life (QOL) questionnaires. Evaluate cost-effectiveness of using 4DCT-ventialtion and VQ scans for pre-surgical assessment. To use longitudinal (pre and post-surgical) 4DCT-ventilation imaging to derive novel post-surgical prediction formulas.
Provision to sign and date the consent form. Stated willingness to comply with all required (non-optional) study procedures and be available for the duration of the study. Be a male or female aged 18 to 100. Patient with lung cancer (presumed or biopsy proven) currently undergoing or having undergone evaluation for resection. Lung function assessment required for pre-surgical evaluation at the discretion of the cardiothoracic surgeon. Life expectancy greater than 3 months.
Exclusion Criteria:
1. Patients getting a planned wedge resection as the only thoracic resectional procedure.
