Density patterns in the normal lung as determined by computed tomography

Radiology. 1980 Nov;137(2):409-16. doi: 10.1148/radiology.137.2.7433674.


Lung density patterns in a group of randomly selected, normal individuals were determined by computed tomography, using two methods: one measuring the density of the peripheral lung (parenchyma), and the other determining the density of the whole lung field. The effects of body position and respiratory phase, as well as patient age were assessed. The potential use for this information in clinical settings and in physiological investigation is suggested.
