There is no significant change in the radiation you receive because of carrying or wearing objects which are not on the area of the body which is scanned. The technologist will make you remove clothing which has metal objects (zippers, jewelry, metal decorations, underwire bras, etc.)
As many you asked, can you wear jeans for a CT scan? The Day of Your CT Scan If you do not wish to change your clothes for the procedure, please wear a loose workout suit or other loose type of clothing that has absolutely no metal of any kind, including zippers or metal-backed buttons.
Considering this, can clothes interfere with CT scan? Preparing for the CT Scan Wear comfortable, loose-fitting clothing to your exam. You may be given a gown to wear during the scan.

What should you avoid before a CT scan?
For four hours prior to your exam, please do not eat solid foods. You may drink fluids such as water, juice, or black decaffeinated coffee or tea. Some CT scan exams, particularly abdominal CT scans, may require that you drink water or an oral contrast so we may better visualize structures within the abdominal area.
Does metal increase radiation?
Metal implants not only deteriorate image quality, but also increase radiation exposure.
Can you drive home after a CT scan with contrast?
You shouldn’t experience any after-effects from a CT scan and can usually go home soon afterwards. You can eat and drink, go to work and drive as normal. If a contrast was used, you may be advised to wait in the hospital for up to an hour to make sure you don’t have a reaction to it.
Do you have to undress for a head CT scan?
For the head scan test, you will need to undress and put on a hospital gown. Some people must have a dye (contrast) injected into the vein in their arm for the CT head scan. The dye contains iodine. This makes it easier for certain parts and functions in your head or neck to show up on the image.
What is the prep for a CT scan?
EAT/DRINK: If your doctor ordered a CT scan without contrast, you can eat, drink and take your prescribed medications prior to your exam. If your doctor ordered a CT scan with contrast, do not eat anything three hours prior to your CT scan. You are encouraged to drink clear liquids.
What does metal do in a CT scan?
When metal hip replacement patients undergo abdominopelvic CT scans, the metal implants produce an area of photon starvation and beam hardening, resulting in dark and bright streaks that may mask important anatomical structures or lesions in the pelvic cavity [2].
What can a CT scan with contrast show?
A special dye called contrast material is needed for some CT scans to help highlight the areas of your body being examined. The contrast material blocks X-rays and appears white on images, which can help emphasize blood vessels, intestines or other structures.
What happens if you eat before a CT scan with contrast?
Why am I not allowed to eat before the CT exam with contrast? If you have food on your stomach, and get an injection of contrast, you could become nauseated. Aside from your discomfort, there is the danger of throwing up while lying down, which could cause the vomit to enter your lungs.
How long does a CT scan take?
A CT scan can take anywhere from 10 to 30 minutes, depending on what part of the body is being scanned. It also depends on how much of your body the doctors want to look at and whether contrast dye is used. It often takes more time to get you into position and give the contrast dye than to take the pictures.
What do you wear for an abdominal CT scan?
You should wear comfortable, loose-fitting clothing to your abdomen and pelvis CT scan. You may be given a gown to wear during the procedure. Metal objects, including jewelry, eyeglasses, dentures and hairpins, may affect the CT images and should be left at home or removed prior to your exam.
