A CT (computerized tomography) scan uses an X-ray beam to obtain detailed images of any part of the body. CT scans are performed using a highly sophisticated CT scanner that produces ultra- thin, slice-like pictures of your body in any dimension or in 3D. CT scans are used to diagnose strokes, blood clots in the lung, and most all diseases of the chest, abdomen and pelvis. They are also a highly diagnostic exam when a patient has suffered trauma to the spine, body or extremities.
CT scans combine a series of cross-sectional X-ray images, or slices, of the organs, bones and other soft tissues. The advanced computer software technology allows the images to be viewed from different aspects, allowing the radiologist (the M.D. who reviews the images and reports the findings back to the ordering physician) to look at each slice individually or in combination, including 3-D volume images. As a result, CT scan images can provide much more diagnostic information than ordinary X-rays.
Low-Dose CT Scans
Fauquier Hospital performs CT scans with two state-of-the-art scanners designed to deliver a significantly lower radiation dose to our patients while maintaining outstanding image quality. CT scans of the body (chest, abdomen, and pelvis) are performed with up to a 70% reduction in radiation exposure and CT scans of the head/brain CT scans typically experience up to a 50% reduction. Since all types of radiation are accumulative in human cells, it is important that radiation exposure be necessary (beneficial) and minimized as much as possible. This is especially important for our pediatric patient population.
The CT scanner in the main Medical Imaging Department also features CT fluoroscopy, which is used to provide guidance when performing interventional procedures or biopsies.
The second CT scanner is located within the Emergency Department to ensure quick access for emergency patients.
Coronary Artery Calcium Scoring CT Scans
A Coronary Artery Calcium Scoring (CACS) scan can detect early signs of heart disease. This non-invasive diagnostic exam is performed on our low-dose CT scanner in the main department and produces highly specialized images of the heart. A board-certified radiologist evaluates the images for calcium (calcified/hard plaque) within the coronary arteries. The measure of plaque is measured against the average, taking age and gender into account. The amount of calcium detected is highly predictive of the amount of coronary atherosclerosis.
Fauquier Hospital offers this self-pay exam for $99. Payment is due at the time of service. Patients are provided a copy of their scan, along with their initial score.
