During the Exam

You will lie on your back on a long table for the exam and will be asked to lie very still as the table slides through the middle of a large machine which creates the lung images. The table goes through the machine initially to determine the scan’s starting point. When it is time to start the scan, you may be asked to hold your breath briefly so a clear picture of your lungs can be obtained. You may hear the machine make clicking or knocking noises.

The actual scan takes less than a minute. You can expect your appointment to last about half an hour.
