Research Abstract

We developed pulmonary function test using chest computed tomogram (CT). Previous study using conventional CT showed that CT value form -1024 to -200 HU as A200 indicated total lung volume and CT value from -1024 to -920 HU as A910 indicated total volume of bullous change. EVV (A200-A910) and IVR (A910/A200) also showed an additional information of CT pulmonary test. We also showed these factors by conventional CT could apply to factors by helical CT. Comparison of pulmonary function between spirometry as conventional pulmonary function test and CT pulmonary function test was evaluated in 32 lung cancer cases. Correlation between A910 and FEV1.0, A200 and VC was found (P=0.032). Correlation between A910 and %FEV1.0 (p=0.0118), IVR and V50 (p=0.0227) was also found. Helical CT pulmonary function test provided shorter examination time than conventional CT test (110 minutes vs. 12 minutes) and showed target area as 3D graphics. Comparison of ventilation-perfusion scintigram using SPECT and CT pulmonary function test was evaluated. A little correlation between A200 and SPECT (p=0.053), IVR and SPECT (p=0.05) was found. CT pulmonary function test had additional information of pulmonary function.
