Eleven patients, mean age 62, considered for lobectomy for lung carcinoma underwent regional quantitative ventilation/perfusion scintigraphy. Preoperative selection criteria included an FEV{sub 1} (forced expiratory volume) of 55% predicted or less, and/or an FEV{sub 1}/FVC% (forced vital capacity) of <70%. A patients underwent a complete set of pulmonary function tests including flow rates, lung volumes, diffusing capacity and blood gases. The statistical correlation between the predicted postoperative FEV{sub 1} and actual yielded an r value of 0.67 with a p value of 0.56. There was good correlation between the predicted postoperative FEV{sub 1} utilizing scintigraphy and the actual, but in several cases the predicted postoperative FEV{sub 1} was underestimated. Although the degree of underestimation is insignificant, patients may be excluded from lobectomy when their values are marginal.
