[Sixty-four slice spiral CT low-dose chest two-phase scanning for lung density measurement in assessing the pulmonary function in patients with chronic obstructive pulmonary disease].
To explore the value of 64 slice spiral CT (SCT) low-dose chest scanning at full inspiration and full expiration for lung density measurement in assessing the pulmonary function in patients with chronic obstructive pulmonary disease (COPD). ⋯ Sixty-four slice SCT low-dose two-phase scanning density indexes are closely related to the indicators (FEV1% and FEV1/FVC) of clinical lung function tests, which can be used to evaluate the lung function in COPD patients conventiently and accurately.
