How is the exam performed?

LDCT lung screening is one of the easiest screening exams you can have. The exam takes less than a minute. No medications are given, and no needles are used. You can eat before and after the exam. You do not even need to get changed as long as the clothing on your chest does not contain metal. You must, however, be able to hold your breath for at least 6 seconds while the chest scan is being taken.
