ABSTRACT
Objective The study the formative causes of low dense area in lung on CT images during expiration.Methods This group included 15 young volunteers,mean age was 22 years.Thin sections of spiral CT at right middle hilum were scanned at suspended deep inspiration and deep expiration on both supine and prone positions.The density and area of lobes on matching structural images in the middle hilum at deep inhalation and exhalation were measured on the supine and prone.The increasing rate in area and absolute increasing value in attenuation as full inhalation comparing to full exhalation were calculated.Results Changes of distention and density in the same section of the right lower lobe on dependent position were greater than that on nondependent one.Correlation between distention and density of the lobes was high(P
