LOINC description : A chest computed tomography (CT) is a non-invasive test that shows the size, shape,
and structure of the lungs and other structures in the thorax. The chest CT scanning
machine takes many pictures, called slices, of the lungs and the inside of the chest.
A computer processes these pictures to be viewed on a monitor or printed on film.
The computer can also stack the pictures to create a very detailed, three-dimensional
(3D) model of the organs. This three-dimensional digital information can be used to
measure the dimensions of the structure, such as the bronchial tree, or the density
of the structure, such as the lung parenchyma. It is very important that the CT scanner
used in any clinical research study be calibrated regularly against calibration standards
that are provided by the manufacturer or in some instances by the study itself.;
