Computed Axial Tomography (CAT, or CT, Scan) is a method of body imaging in which a thin X-ray beam rotates around the patient, small detectors measure the amount of X-rays that make it through the area of interest, and then a computer uses this data to construct a 2-D cross-sectional image.
These cross sections can be reconstructed to form a 3-D image, for better visualization and interpretation.
Low Dose Scans
Our CT machine is equipped with Low Dose software that maximizes image quality while reducing the X-ray dose. This means that we are reducing radiation exposure while maintaining and improving image quality.
The following article explains more about why we choose low dose software.
- You will be asked to lie on a table that will slide into the scanner. Depending on the particular study, you may have to lie on your stomach, back, or side. If the study is ordered with contrast, it will be at this time that a small IV will be placed into your hand or arm.
- During the test it is important to remain as motionless as possible, or the images will come out blurred. The CT technologist will give instruction on when you should hold your breath and not move.
- Generally the scan will only take a short time, but if contrast-enhanced or higher-resolution images are ordered, it will take longer.
