Health Scan™ is the screenings program for Medical Imaging of Fredericksburg, a member of the Mary Washington Healthcare family of services. This program now offers three preventative screenings for colorectal cancers, heart disease, and lung cancer. Health Scan™ uses advanced technology to identify risks early, allowing you to take action early.

Fast and Convenient



CT stands for Computed Tomography, which uses special x-ray equipment to help detect a variety of diseases and conditions. CT scanning is fast, painless, noninvasive and accurate. The cross-section images collected during a CT scan are arranged for the radiologist by special computer software and can even generate three-dimensional images. These images are viewed on a computer monitor with highly detailed images. CT images of internal organs, bones, soft tissue and blood vessels provide more detail than x-rays, particularly of soft tissues and blood vessels.

With this specialized equipment and local expertise Health Scan™ creates and interpret CT scans of the body, allowing our radiologists can more easily diagnose problems such as cancer, cardiovascular disease, colon and lung disorders.

Radiation Safety

Patients sometimes wonder about the amount of radiation they will receive, but all three tests are safe. The radiation dose for these scans is equivalent to living a year in Denver and being exposed to the natural background radiation found there.

Lung Scan

Our CT scanner takes hundreds of images of your chest in a matter of seconds. Multiple images are obtained during one breath-hold. The scan takes about 10 minutes to complete. Immediately after the scan, you will receive a consultation with a radiologist who will read and interpret your Lung Scan images. You and your physician will receive a detailed report of the findings and recommended action.


A DEXA Scan, also called a bone density scan, uses dual-energy X-ray absorptiometry. The x-rays pass through your bones and what is not absorbed is detected on the other side of the body. This allows doctors to determine the density of your bones. In turn it can help doctors diagnose osteoporosis and other conditions.

Heart Scan

Using a high-speed CT scanner, we look inside the heart and its arteries for calcium build-up. This measures and scores the amount of calcium in the coronary arteries and helps determine your risk for heart disease. The Heart Scan also detects plaque years before stress testing. The Heart Scan is painless and takes less than 30 minutes including time to meet with a radiologist to view your results.

Virtual Colonoscopy

Unlike a traditional colonoscopy, our virtual colonoscopy does not require anesthesia, IV lines, or a colonoscope. Instead, you lie on the scanning table for about 10 minutes. Air is introduced into the colon. This allows distention of the colon to enable the scanner to take accurate images of the colon.
