Some CT exams will require you to remove hearing aids and removable dental work. Women will need to remove bras containing metal underwire. You may need to remove any piercings, if possible.

Your doctor may instruct you to not eat or drink anything for a few hours before your exam if it will use contrast material. Tell your doctor about all medications you are taking and if you have any allergies. If you have a known allergy to contrast material, your doctor may prescribe medications to reduce the risk of an allergic reaction. To avoid unnecessary delays, contact your doctor well before the date of your exam.

Also tell your doctor about any recent illnesses or other medical conditions and whether you have a history of heart disease, asthma, diabetes, kidney disease, or thyroid problems. Any of these conditions may increase the risk of an adverse effect.

In rare cases, the dye may cause a life-threatening allergic response called anaphylaxis. If you have any trouble breathing during the test, tell the scanner operator right away. Scanners come with an intercom and speakers, so someone can hear you at all times.

Disadvantages Of Ct Scans

While CT has advantages, it is not perfect. The amount of radiation you experience from a computed tomography scan can be up to 1,000 times more than you get from an x-ray. Even at these levels, the radiation is a small dose, but if you require multiple scans over your lifetime, it can add up. Despite costing less, CT images dont capture as many details as MRIs, and the doctor may miss some crucial pieces of information.

While CT machines can accommodate larger patients, there is still a limit. Traditional scanners can allow for patients up to 450 pounds, depending on the model. The patients back to front measurement across the widest point should also measure less than 28 inches.

Types Of Ct Scans: Ct Scan With Contrast Vs Ct Scan Without Contrast

MRI Scans with Contrast and How They Differ From MRI Scans Without ...

In general terms, there are two types of CT Scans: CT Scans with contrast and CT Scans without contrast.

CT Scan with contrast:

a CT Scan with contrast is an imaging study in which contrast material is used to help highlight parts of your body that need a detailed and exact examination. In this case, the contrast material helps to paint your organs and blood vessels in a white tone. In order to do so, the contrast material helps to block the X-rays being transmitted through these parts of your body. Accordingly, if needed, the contrast material will be administered to you in different ways, depending on the part of your body thats being studied. In general, contrast material can be given to you in three ways: you may have to drink a liquid containing the contrast, the contrast may be injected through a vein in your arm, or it may be administered via an enema. Most often, the constrast material that is used in CT scan studies with contrast is called Optiray. Optiray is a radiopaque contrast material that contains iodine, a substance that absorbs X-rays and helps to generate accurate images of specific organs.
