How to Prepare for a CT Scan

A CT Scan is a medical imaging test that uses computer technology to create detailed images of the interior of the human body. These tests are performed by personnel known as radiology technologists and radiographers. This article discusses some of the important benefits of having a CT Scan and how to prepare for it. Although the test is quick and relatively painless, patients may find it uncomfortable. For this reason, it is imperative to have a good understanding of how a CT Scan is performed.

CT scans are quick

A CT scan is a medical test that uses X-rays to produce detailed images of internal organs and structures. CT scans are quick, painless, and generally safe. However, CT scans are not without risks. A patient may have to drink a special contrast medium, which is either given as a drink or is injected into a vein. The contrast medium may depress kidney function. The procedure can take 20 minutes or more, depending on the severity of the problem.

painless

While the CT scan itself is not painful, there may be some discomfort associated with an IV contrast agent. Your CT technician will likely insert an IV line, usually into your groin or arm, to give you a contrast agent. Your doctor may also ask about any metal devices or medication patches you have, or allergies you have. The procedure usually lasts for about 15 minutes, and you will be asked to change into a hospital gown.

relatively safe

Although a CT scan can be extremely useful for diagnosing various health issues, it is relatively safe, especially when performed sparingly. CT scans expose patients to low levels of ionizing radiation, which can cause cellular mutations and cancer. However, pregnant women should speak to their doctor about the benefits and risks of CT scans to decide if they should undergo one. In addition, some women may be allergic to the contrast dye, which can have negative side effects if ingested.

they can be uncomfortable

While a CT scan is relatively painless, the procedure can be a bit uncomfortable. For example, the technologist may ask you to drink only clear liquids beginning at midnight on the night before the scan. Similarly, you should avoid eating for about four hours before your appointment. However, some body parts can be scanned without a fast-food meal. If you are unsure if you should eat before your appointment, discuss your concerns with the technologist.

they involve small doses of radiation

While CT scans use small doses of radiation to produce detailed images, the amount of radiation is much higher than that of a typical x-ray. This increased exposure can have short and long-term effects. Nevertheless, CT scans are a valuable diagnostic tool, allowing doctors to see parts of the body that a common x-ray cannot see. The type of radiation exposure you receive during a CT scan depends on the reason you need the procedure. Your healthcare provider will discuss the risk factors and benefits of CT scans with you.

they can be expensive

A CAT scan can be costly, so it is important to know the costs involved before booking an appointment. Costs are typically broken down into technical fees and professional fees. Technical fees include the cost of the equipment, repairs, upgrades, and wages paid to physicians and technicians performing the scan. Professional fees also include rent or lease costs and administrative costs. The cost of a CAT scan is typically higher for those without insurance. The amount of out-of-pocket expense will vary depending on the type of health plan you have.

they can be done by a radiology technologist

A radiology technologist is a health care professional who performs a CT scan. They work in a large, doughnut-shaped machine that rotates around the body, causing X-rays to be emitted from the body. Because the images are so detailed, a CT scan is useful for diagnosing abnormalities in almost any part of the body.
