Postoperative percent FEV<sub>1</sub> (po%FEV<sub>1</sub>) was then predicted from the fractional lung volume determined on semiquantitatively assessed non‐CE‐ and dynamic CE‐perfusion MRIs, from the functional lung volumes determined on quantitative CT, from the number of segments observed on qualitative CT, and from uptakes detected on perfusion scans within total and resected lungs. Predicted po%FEV<sub>1</sub>s were then correlated with actual po%FEV<sub>1</sub>s, which were %FEV<sub>1</sub>s measured postoperatively. The limits of agreement were also determined.</p> </sec> <sec id="jmri24800-sec-0003" sec-type="section"> <title>Results</title> <p>All predicted po%FEV<sub>1</sub>s showed significant correlation (0.73 ≤ <italic>r</italic> ≤ 0.93, <italic>P</italic> < 0.0001) and limits of agreement with actual po%FEV<sub>1</sub> (non‐CE‐perfusion MRI: 0.3 ± 10.0%, dynamic CE‐perfusion MRI: 1.0 ± 10.8%, perfusion scan: 2.2 ± 14.1%, quantitative CT: 1.2 ± 9.0%, qualitative CT: 1.5 ± 10.2%).</p> </sec> <sec id="jmri24800-sec-0004" sec-type="section"> <title>Conclusion</title> <p>Non‐CE‐perfusion MRI may be able to predict postoperative lung function more accurately than qualitatively assessed MDCT and perfusion scan.
