MRI OVERVIEW
What Is An MRI?
Magnetic Resonance Imaging (MRI) is a type of imaging that uses magnetic fields and radio waves to generate images of the body. MRI has become a very valuable diagnostic tool detecting everything from cancer, heart and vascular disease, strokes, and disorders of the joints and musculoskeletal system. Of equal significance is the ability for physicians to avoid unnecessary surgery and more invasive diagnostic procedures. MRI technology produces extremely detailed images of body tissue, organs and bones without the need for radiation.
Electromagnetic energy is released when exposing a patient to radio waves in a strong magnetic field which is then measured and analyzed by a computer producing two and three-dimensional images. The MRI scanner creates a strong magnetic field through the body, and then it sends radio waves into the body and assesses the response sent back from the different tissues. Under the influence of the magnetic field, different tissues send back different responses to the radio waves. Also, certain diseased or injured tissues send responses that are different from healthy ones. A computer in the scanner processes the different responses, and where they came from, into images of the body. These are displayed as slices, like slices through an orange or a loaf of bread. The images are sent to the radiologist for interpretation.
Preparation For MRI
As part of the preparation for the exam, you will be asked if you have any items that can cause some restrictions when having an MRI. These can be metal implants such as pain pumps, metal clips or coils surgically implanted to control aneurysm bleeding, pacemakers to control your heart beat, or cochlear implants for your hearing. If you have any of these items please inform the MR scheduling staff when you make the appointment. When you arrive at the imaging center you will again be asked if you have these implants.
CinemaVision Can Soothe Your Claustrophobia
Fall in love with MRI through Cinemavision! Completely forget about you surrounding while watching a DVD, broadcast television, or listening to an iPod, internet radio or an MP3 player while undergoing an MRI scan. MRI goggles are perfect for patients who suffer from claustrophobia and parents who are concerned about child sedation. MRIs can be lengthy and noisy, but Cinemavision ensure patients have a comfortable imaging experience.
Can I get an MRI if I have a pacemaker?
Most likely, yes!
Contra Costa Imaging Center works closely with the local Cardiology community to provide much-needed access to MRI exams for patients with most types of pacemakers and implanted cardiac defibrillators (ICD’s). We will need to research the specifics of your implanted device and verify its MRI eligibility with your Cardiologist and device manufacturer prior to your exam. If your device is deemed eligible, Contra Costa Imaging will then coordinate to have a representative from your device manufacturer available at the time of your MRI to place your cardiac device into a special MRI mode for your exam, they will then return your device back into its normal mode after your exam is complete. During your MRI your vital signs will be monitored by an ACLS nurse who will be with you in the MRI department the whole time.
Please contact us and we will be happy to work with you and your Cardiology team to get the process started.
MRI FAQs
1. Do I need an IV?
The MRI order from your doctor will specify if your exam will require contrast. Contrast is administered via intravenous injection.
2. What is MRI Contrast and what does it do?
MRI contrast, or dye, is used to take a closer look at inflammation, blood vessels, and organs.
3. How is MRI different than CT or X-ray?
An MRI best examines soft tissues, ligaments, tendons, the spinal cord, and the brain . CT exams provide cross-sectional imaging of organs, tumors, sinuses, lungs, the heart, and even blood vessels. X-rays are simple two-dimensional images of structures in the body.
4. I have a PPO insurance plan, why do I need authorization?
Most health insurance plans require an authorization review in order to ensure that the ordered MRI is the appropriate exam for your health condition.
5. How big is the actual MRI?
Most MRI machines are 60 cm wide. Please ask your MRI provider if they have a wide-bore on site.
6. What is our MRI facility doing to keep you safe?
You will be given a new mask upon checking-in, which you’ll wear during your entire visit.
We are sanitizing all surfaces, shared spaces, dressing rooms and equipment after each exam.
If you’re symptomatic on the day of your appointment, your exam will be postponed. Special arrangements will be established for urgent exams.
We are limiting the number of patients allowed in our waiting rooms; physical distance of six feet.
7. How much will my MRI cost out of pocket?
Please speak to your MRI provider about their rates.
8. I think I’m allergic to MRI contrast..
MRI contrast is called, MR-Gadolinium. This is not the same contrast used in CT (Barium sulfate).
9. Is the MRI exam going to be loud?
Yes. We will provide you with ear plugs or MRI-compatible headphones which we can connect to your smart-phone.
10. Why do I have to remove my jewelry? What about my bra?
The MRI is a powerful magnet which will attract all metal objects. This imposes a safety risk with even the smallest piece of metal in the room.
11. Can I bring in my tablet/music device?
Yes. We can connect our MRI-compatible headphones to your device.
12. How much radiation will I receive with MRI?
MRI does not involve any radiation.
13. Can my family member go into the scan room with me?
For safety reasons, we may not allow any additional people into the MRI exam room.
14. I have another body part bothering me, can I add that to my exam today?
We will provide imaging as ordered by your physician.
We will also need to know if you are pregnant.
Although it is safe to scan patients that are pregnant, it is important that we know so we may inform you of the latest literature.
Exam Time
The length of the exam varies, but most exams can be completed in 30 minutes. If you have multiple exams, each exam takes approximately 30 minutes.
Exam Results
After your exam, the radiologist will review your images and a report will be sent directly to your physician. Reports are available within 24 to 72 hours.
