Here are some common questions you may have about your procedure or appointment.

MRI
FAQs

What is an MRI?

MRI (Magnetic Resonance Imaging) is a noninvasive diagnostic tool used to identify and treat various medical conditions. These exams provide unparalleled views of internal body structures including the organs, soft tissues and bone, which cannot be seen using conventional X-rays or CT scans.

MRI technology produces clear and precise cross-sectional images. This diagnostic tool offers a quick and safe method for gathering pictures of the human anatomy allowing physicians to detect many conditions in earlier stages.

How does an MRI work?

MRI technology uses a magnetic field and radio waves to produce detailed pictures of the human body. As the radio waves pass through the body, images are created on a computer screen for radiologists to analyze. These precise images allow radiologists to view soft tissue (muscles, fat, internal organs, blood vessels and tendons) and bones without the use of X-rays or surgery.

Is an MRI safe?

The MRI imaging technique does not involve exposure to radiation. However, women should always inform their technologist if there is a chance they could be pregnant. Medical and electronic devices may interfere with MRI exams and pose a potential risk. Patients with any kind of metallic implant should not have an MRI unless their physician is aware of the device and has approved the procedure. Patients with pacemakers should not undergo an MRI.

What if I am claustrophobic and don't like to be in enclosed spaces?

The MRI team will work with patients who suffer from claustrophobia.

Music of your choice is provided in the MRI suite to help patients relax during their scan.

Many patients request a mild sedative prescription when coming in for their MRI procedure. This can be given to the patient only if requested at least 24 hours prior to scheduled appointment and must arrange for a responsible adult to drive them home. Restrictions may apply.

Can pediatric patients receive an MRI?

Yes, children can receive an MRI; however, sedation is not provided. The patient must be able to hold still during the entire scan.

Parents can accompany their children into the scan room and remain with the child during the MRI exam.

We have an Open MRI machine in our South Ogden and Pleasant Grove locations. This magnet provides more open space compared to the traditional MRI magnet. This allows for the parent to lie next to their child if they prefer.

Will I receive an IV?

Depending on the type of exam, patients may receive a contrast agent (gadolinium) intravenously (IV) through a vein in the arm or hand. Contrast mediums or contrast agents are safe injections used to enhance organs and blood vessels to help the radiologist see tissue that is hard to detect.

If your physician or radiologist has determined that an IV is needed for your MRI, you will receive an IV in your arm or hand prior to the test so the technologist can administer the contrast agent at the time of your scan.

Should I take my medications the day of my MRI?

Yes, it is important for patients to continue taking all medications prescribed by their physician before their MRI exam. Patients should let their technologist know what medications they have taken prior to their MRI scan.

Can I eat and drink before my MRI?

Yes, everything can be done as normal prior to MRI procedure.

How should I dress for my MRI?

MRI compatible clothing will be provided to patients in addition to a dressing room and locker. If the patient does not want to the provided clothing and locker, patients should dress in loose-fitting, comfortable clothing such as a sweatshirt and pants without metal snaps or zippers. All valuables should be left at home.
Jewelry, glasses, hearing aids, dentures, hairpins, credit cards, coins, keys and other metal objects will need to be removed and placed in the provided locker before going into the MRI room. Metal cannot enter into the MRI room. If you have questions, please consult with an MRI technologist prior to your exam.

How long will my MRI scan take?

MRI scans are individualized and tailored to each patient’s needs. Total scan times range from 30 to 60 minutes per exam.

Patients who require a contrast agent will be given the IV injection after their preliminary scans. The patient will then return to the examination table to continue the scan. Pictures are needed before and after the IV injection when a contrast agent is used.

What happens after my MRI?

Patients will be given a CD or Films (requested by their doctor) and may leave immediately following their MRI scan, going about their normal activities. Radiologists at U.S. MRI know that rapid results are essential for each patient’s peace of mind and so physicians can begin planning treatment immediately.

After each MRI scan, a U.S. MRI radiologist reads the images, and a report is available to your doctor via our referring physician portal with real time results. Your doctor will provide you with your results at your follow-up appointment.

X-Ray

What is an X-Ray?

X-rays are a type of radiation called electromagnetic waves. X-ray imaging creates pictures of the inside of your body. The images show the parts of your body in different shades of black and white. This is because different tissues absorb different amounts of radiation. Calcium in bones absorbs x-rays the most, so bones look white. Fat and other soft tissues absorb less, and look gray. Air absorbs the least, so lungs look black.

How does an X-Ray work?

This beam travels through the air, comes into contact with our body tissues, and produces an image on a plate. Soft tissue, such as skin and organs, cannot absorb the high-energy rays, and the beam passes through them. Dense materials inside our bodies, like bones, absorb the radiation.

Is an X-Ray safe?

The amount of radiation you’re exposed to during an X-ray depends on the tissue or organ being examined. Sensitivity to the radiation depends on your age, with children and elderly being more sensitive than adults.
Generally, however, radiation exposure from an X-ray is low, and the benefit from these tests far outweigh the risks.

What if I am pregnant?

If you’re pregnant or suspect that you may be pregnant, tell your doctor before having an X-ray. Though the risk of most diagnostic X-rays to an unborn baby is small, your doctor may consider another imaging test, such as ultrasound.

How should I dress for my X-Ray?

X-Ray compatible clothing will be provided to patients in addition to a dressing room and locker. If the patient does not want to the provided clothing and locker, patients should dress in loose-fitting, comfortable clothing such as a sweatshirt and pants without metal snaps or zippers in the region we are pefrorming X-Rays on. All valuables should be left at home.

How long will my X-Ray scan take?

X-ray scans are individualized and tailored to each patient’s needs. Total scan times range from 10 to 15 minutes per exam.

What happens after my X-Ray?

Patients will be given a CD or Films (requested by their doctor) and may leave immediately following their X-Ray scan, going about their normal activities. Radiologists at U.S. MRI know that rapid results are essential for each patient’s peace of mind and so physicians can begin planning treatment immediately.

After each X-Ray scan, a U.S. MRI radiologist reads the images, and a report is available to your doctor via our referring physician portal with real time results. Your doctor will provide you with your results at your follow-up appointment.

CT

What is a CT?

CT, or CAT scans, are special X-ray tests that produce cross-sectional images of the body using X-rays and a computer. CT scan images allow the doctor to look at the inside of the body and create pictures of your organs, bones, and other tissues. It shows more detail than a regular X-ray.

How does an CT work?

They use a narrow X-ray beam that circles around one part of your body. This provides a series of images from many different angles. A computer uses this information to create a cross-sectional picture.

Is a CT safe?

CT scans use X-rays, which produce ionizing radiation. Sensitivity to the radiation depends on your age, with children and elderly being more sensitive than adults.

Generally, the benefit from these tests outweigh the risks.

What Is a CT Scan with Contrast?

In a CT scan, dense substances like bones are easy to see. But soft tissues don’t show up as well. They may look faint in the image. To help them appear clearly, you may need a special dye called a contrast material. They block the X-rays and appear white on the scan, highlighting blood vessels, organs, or other abnormalities.

Contrast materials are usually made of iodine or barium sulfate. You might receive these contrast agents in one or more of two ways:

  • Injection: The contrast is injected directly into a vein.
  • Orally: Drinking a liquid with the contrast material can enhance scans of your digestive tract.
Can pediatric patients receive a CT?

Yes, if a physician has deemed a scan medically necessary, we can perform a CT. However, we have found that some pediatric patients may be nervous or scared to have medical imaging done. If that is the case, we recommend pediatric IV sedation from Primary Children’s Hospital.

Should I take my medications the day of my CT?

If you are getting a CT scan without contrast, you may continue taking all medications as normal. If you are receiving any type of contrast, this varies on each exam, please call U.S. MRI prior to the day of your appointment to verify if you may continue your medications.

Can I eat and drink before my CT?

If you are getting a CT scan without contrast, yes, everything can be done as normal prior to the CT procedure. If you are receiving oral contrast prior to your exam, you may not eat or drink anything 4 hours prior to your exam time. If you are unsure what type of exam you are receiving, please contact U.S. MRI the day before your appointment for clarification.

How should I dress for my CT?

CT compatible clothing will be provided to patients in addition to a dressing room and locker. If the patient does not want to the provided clothing and locker, patients should dress in loose-fitting, comfortable clothing such as a sweatshirt and pants without metal snaps or zippers. All valuables should be left at home.

Jewelry, glasses, hearing aids, dentures, hairpins, credit cards, coins, keys and other metal objects will need to be removed and placed in the provided locker before going into the CT room.
If you have questions, please consult with a CT technologist prior to your exam.

How long will my CT scan take?

CT scans are individualized and tailored to each patient’s needs. Total scan times range from 10 to 30 minutes each exam.

Patients who require a contrast either IV and/or oral contrast prior to their exam, might require additional time in office.

What happens after my CT?

Patients will be given a CD or Films (requested by their doctor) and may leave immediately following their CT scan, going about their normal activities. Radiologists at U.S. MRI know that rapid results are essential for each patient’s peace of mind and so physicians can begin planning treatment immediately.

After each CT scan, a U.S. MRI radiologist reads the images, and a report is available to your doctor via our referring physician portal with real time results. Your doctor will provide you with your results at your follow-up appointment.
