Lung function imaging under quantitative spirometrically controlled CT.

OBJECTIVE To assess the possibility of using spirometrically controlled computed tomography (CT) to test pulmonary ventilation function. METHODS Spiral CT scans under the control of a spirometer were performed on 30 healthy adults. Spiral CT scan was performed at 50% vital capacity (VC) with an 8 mm slice thickness. Mean attenuation values and pixel index… (More)
