High Resolution Chest CT - About the Exam

High resolution chest CT imaging can detect interstitial lung disease (ILD). ILD involves the use of special CT scanning to view the parenchyma, the functional parts of the lungs. High resolution chest CT is chosen to maximize spatial resolution. It usually involves additional images taken after fully breathing out, and may include images in the prone or “face down” position.

What you can expect during a high resolution chest CT:

You will be asked to lie on the examination table, where you initially be positioned face up.
The table will start moving, first slowly and then relatively more rapidly when the actual CT is performed.
When the examination is completed, you will be asked to wait until the technologist verifies that the images are of high enough quality for accurate interpretation.
The CT examination is usually completed within 30 minutes.
Most often, no contrast is administered.
