CAT scans (or CT scans) allow us to look inside the body using a special X-ray camera. The CAT scan is regarded as the "gold standard" for looking at the chest, abdomen and pelvis. The brain and spine can be imaged, as well. With the speed and technology of our ultramodern CAT scan machines, we can get highly detailed images that help us pinpoint potential health problems at a much earlier stage than in the recent past.
