CT Scans in Madison, CT

What is a CT scan?

A CT scan (aka CAT scan or computerized tomography) is an X-ray procedure that is enhanced by a computer. The results are 3-dimensional "slices" or scans through a body part showing bone and body tissue. Numerous scans are taken to make up a complete exam.

How it works

You will be positioned on the scanning table that slides into a donut-shaped gantry. It is not tunnel-like nor is it enclosed. As each scan is done, the table slowly moves you back out of the gantry. The technologist will give you breathing instructions if necessary. The technologist is always in contact with you via a two-way microphone. You will not be alone! Some CT scan examinations require the use of a contrast media. This may be given by mouth and/or injected into a vein. These substances are given to highlight various body parts.

A CT scan takes about 30-60 minutes, depending on the type of scan needed. This allows for preparation time as well as time for the computer to generate the images. Actual exposure time to radiation is minimal. The CT scan machine used at Madison Radiology is a spiral CT scanner. This machine is able to scan continuously, allowing for faster and more accurate examinations. An entire abdomen and pelvis scan can be completed in approximately 5 minutes with this technology.
