There is no special preparation required for a low-dose CT lung screening. You may take your daily medications as prescribed. However, please tell your provider if you are or might be pregnant.
The screening will be performed by a radiologic technologist, and a board-certified radiologist will interpret the results.
During the test, you will lie on your back on a table that is attached to the CT scanner. The table will slide into the opening in the scanner while a cylinder rotates around your body. You may hear a low whirling sound, and the table will move slightly during the exam.
You will be asked to hold your breath for about 15 seconds while images are taken. Be sure to hold completely still while your lungs are being scanned to avoid the need for repeat images.
During the test, you will be alone in the scan room, but the technologist will watch you through a window and you will be able to communicate through an intercom.
The scan takes only a few seconds, but please allow 30 minutes for the entire examination.
