Frequently Asked Questions
The revolutionary design of FONAR’S Upright MRI allows patients to simply walk in, sit down, and watch TV during the scan. The Upright MRI allows all parts of the body, particularly the spine and joints, to be images in a weight-bearing state.
Magnetic Resonance Imaging is very safe. There are no health risks associated with the magnetic field or the radio waves used by the machine. However, some special circumstances limit the use of a magnetic field. It is important for you to tell us if you have any of the following:
- Cardiac pacemaker or artificial heart valve
- Metal plate, pin or other metallic implant
- Intrauterine device, such as Copper and IUD
- Insulin pump or other infusion pump
- Aneurysm clips
- Previous gun wound
- Inner ear implant
- Metal fragments in your eye or other parts of your body
- Permanent (tattoo) eyeliner
No special preparation is needed. You can eat normally and take medication as usual, unless your doctor has given you other instructions. You may find it easier to relax if you avoid drinking coffee or other caffeinated beverages prior to your exam.
A MRI technologist will ask about your symptoms and then describe your scan. If you have any questions you may ask the technologist at this time. While in the machine, it will make a noisy, knocking sound during the test. Earplugs are available upon request. During your scan, it is very important for you to remain as still as possible for the best image quality. Your only job is to relax and watch TV during this time. (Lockers are provided for your convenience)
The length of the exam depends on the type of MRI exam your doctor has ordered. Most exams are completed within 30 to 60 minutes.
This examination will enable your doctor to better visualize a joint in your body, more than a routine MRI. A MRI arthrogram is a radiographic procedure in which a radiologist injects contrast material into the joint before the MRI exam is completed.
First the technologist will explain the procedure and you will need to sign a consent form. Next, the radiologist will cleanse the area over the joint and the skin will be numbed with a local anesthetic (this may burn for a moment). The radiologist will use X-ray fluoroscopy to place a needle into the joint and to observe the contrast material being injected into the joint. You will then be taken over to the MRI suite for the completion of the exam. The technologist will be observing you and giving you instructions during the exam.
Do not take any blood thinning medications for 72 hours before the arthorgram. These include prescription drugs, aspirin products, and vitamin E. The entire examination should take approximately 60 minutes. If you have any questions, be sure to ask.
You may have some mild discomfort or swelling of the joint following the examination. Following the procedure, you may apply ice if swelling occurs and take a mild pain reliever such as Tylenol. If symptoms continue or worsen, immediately call your doctor.
After your exam, the radiologist will review your images and a report will be sent directly to your doctor. Reports are available within 24-48 hours. Your doctor will discuss the results of the exam with you.
Although MRI is an effective diagnostic tool, certain medical conditions will prevent individuals from having an MRI. Please inform your physician and our center personnel at the time of scheduling if you have any of the following:
- Cardiac Pacemaker
- Implantable Cardioverter Defibrillator (ICD)
- Cochlear Ear Implant
- Aneurysm Clip
Other certain medical conditions may prevent individuals from having an MRI. Please inform your physician and our center personnel at the time of scheduling if you have any of the following:
- Metal fragments located in one or both eyes
- Metal fragments or prosthesis within the body
- Other certain type of electrical or magnetic activated implants
It is very important that if you are pregnant or there is a possibility of pregnancy, or if you are breast feeding, that you inform your physician and the center personnel prior to your MRI.
If any of these conditions exist, your physician and/or the center radiologist will determine if you can be safely imaged or recommend an alternative diagnostic imaging procedure that can be safely performed for your condition.
Safety First: No Pacemakers!
