Dr. Henschke describes the low dose CT (computed tomography) scan and if it can detect lung cancer.
A low dose CT scan is acquired at a low dose. You can use the same equipment to get a high dose scan or a low dose scan. A low dose scan is about the same, gives you about the same radiation exposure as a mammogram, and you could still find very small abnormalities in the lung, as small as a grain of rice.
