Whether you are searching for a walk-in CT scan in your area or simply want more information about how CT scans work, scan.com can ensure success on your journey for accurate medical imaging information. Discover more below about CT scans and how to find a trustworthy medical imaging provider in your area.
What is a CT scan?
Computer topography (CT) machines are computerized X-ray devices that capture detailed images of different areas of your body. Radiographers generally perform CT scans with patients lying down on a bed that slowly enters the opening of the CT machine, or the gantry.
During a scan, CT machines cast narrow beams of X-rays that rapidly rotate around your body. By capturing incremental, cross-sectional pictures, or slices, of the body and then stacking them together, CT scans form 3D images that help doctors identify basic bodily structures, abnormalities, and diseases.
Although bodily material like bone is often easy to see in medical imaging, it can be harder for radiologists to detect soft tissue without the aid of contrast dyes. CT scans, like many other medical imaging methods, use safe contrast agents (some of which are iodine-based) to help improve the visibility of the blood vessels in soft tissue. In turn, this improves radiologists’ ability to see and read your scan.
What can a CT scan detect?
CT scans can help your doctor identify abnormalities in your body - some of which can be dangerous - including tumors, lesions, diseases, blood clots, hemorrhages, and more. With the help of this valuable information, your radiologist or other physician can create a treatment plan tailored to your needs. Radiologists can conduct CT scans on many places of the human body, including (but not limited to) the:
- Adrenal glands
- Cervical spine
- Lumbar spine
- Thoracic spine
- GI tract
How much does a CT scan cost?
The cost of a CT scan depends on a variety of factors, including whether you use insurance to pay for your scan, your particular provider, the scope of your scan, and more. To figure out how much your CT scan will cost, you can contact the imaging center directly to inquire about the price. If you would like to use your insurance benefits to pay for your scan, you may also ask your health insurance company about coverage and expected costs.
CT scan safety & risks
CT scans are FDA-approved and generally safe. They provide physicians with valuable information that can aid in the diagnosis and treatment of some dangerous conditions. However, some level of risk accompanies almost every medical procedure, including medical imaging scans.
CT scans use X-rays to capture images of the body. X-rays produce onizing radiation, which can impact living tissue. Though the risk for developing cancer due to ionizing radiation is low, the impact of CT tests can accumulate with repeated exposure. This means there is a potential increase in risk for biological tissue damage when getting multiple scans. Still, radiographers do everything in their power to limit radiation exposure in a CT scan.
Before your scan, be sure to tell your doctor whether you live with any medical conditions, such as kidney dysfunction.
