Secondarily, the predictions made using traditional scintigraphic data will be compared with those from the new algorithm in a subset of high-risk patients, and cumulative contrast media and irradiation doses associated with imaging will be presented. How other measures of pulmonary function (e.g. transfer factor of the lung for carbon monoxide (TLCO)) and the presence/absence of operative complications might be predicted will also be investigated. Additionally, the potential links between (i) pre-surgical imaging data, (ii) post-surgical changes in respiratory function, and (iii) changes in health related quality of life will also be explored.
