A CAT scan is a large x-ray that also combines a computer to process images. CAT scans can look at organs, blood vessels and bone. A CAT scan is good at diagnosing a variety of medical conditions, from traumas, cancer, appendicitis, diverticulitis or nodules.

During a CAT scan, the CAT scan technologist helps the patient onto a moveable table, and helps make the patient comfortable. The table moves inside the scanner and the technologist leaves the room. Behind the scenes, the CAT scan technologist starts the scanner and takes the pictures. Most CAT scans take only a few minutes. The technologist comes back into the room, helps the patient off the table, and the CAT scan is complete for the patient.

After the patient leaves, the CAT scan technologist will process the images. Next, the technologist sends the CAT scan images to the radiologist – a physician who specializes in medial imaging. The radiologist is the doctor who reviews the exam to determine a diagnosis.
