CT (CAT Scans)
A computed tomography (CT) scan or CAT scanning maps the structure or anatomy of organs and provides an image of how they look. It is one of the most common imaging exams used by New Haven Radiology.
The scanner combines a special X-ray machine with computer modeling software to generate images of "slices" of internal organs. An increasing number of detectors generating hundreds to thousands of images are then combined, giving physicians a clear picture of internal body structures, even in 3D formats. The latest advances in CT technology have improved the way the X-ray beams are focused and increased the speed so that the X-ray beam can rotate around a patient in less than five tenths of a second and can record multiple pieces of information at once.
Preparing for your exam:
You'll be lying down on a padded table for 10 to 15 minutes, so wear loose-fitting, comfortable clothes preferably without zippers, snaps or other metal fasteners as they can interfere with the image. The technician may ask you to remove eyeglasses, dentures, hearing aids, hair clips or other items that may also effect the scan. In some cases, you may be asked to abstain from food and water prior to your exam. Women who may be pregnant must inform their physicians.
During the exam
Your technologist will give you prompts about breathing and other simple instructions during the exam.
