Role of High-resolution Computed Tomography in Evaluation for Patients with Chronic Obstructive Pulmonary Diseases / 中国康复理论与实践

ABSTRACT

@#Objective To investigate the evaluation of high-resolution computed tomography (HRCT) in patients with chronic obstructive pulmonary diseases (COPD), and the relationship with the pulmonary function test and BODE index.Methods 32 COPD patients and 22 normal controls were examined by pulmonary function test (PFT) and HRCT. The data of two groups were compared.Results The volume and pixel index (PI) in forced expiration were higher in the COPD group than those in the control group ( P<0.01), but there was no significant difference in Vin between two groups ( P>0.05). In the COPD group, Vex and Vin were negatively correlated with FEV1/FVC ( P<0.05) respectively. There were no correlation between Vin, Vex and FEV1% pre in the COPD patients ( P>0.05) respectively. Vin and Vex were not correlated with BODE index (all P>0.05) respectively. The ratio of Vex/Vin was positively correlated with BODE index ( P<0.05), and not correlated with FEV1/FVC ( P>0.05). PI910ex was positively correlated with BODE index ( P<0.01), and negatively correlated with FEV1%pre, FEV1/FVC (all P<0.05) respectively.Conclusion The pulmonary function of COPD patients can be evaluated by HRCT, especially by PI910ex.
