An MRI Scan (magnetic resonance imaging) is a painless technique that allows doctors to look at the soft tissues of the body.
It is used to gather important information about your brain, spine, joints or other internal organs. It helps study nerves, muscles, ligaments, bones, and other tissues. These studies are used to evaluate the possible presence injuries to these areas. MRI’s use magnetic fields and radio waves to obtain incredibly detailed images of the human body.
Envision Imaging offers several options for your MRI procedure:

Open MRI Scans – High-Field (1.5T)
The High-Field MRI 1.5T field strength delivers outstanding image quality.
An "Open" MRI simply refers to the way the equipment is configured. An Open MRI is open on three sides, creating a very roomy, bright imaging experience. This MRI provides a modern design, yielding fast, comfortable exams.
High-Field refers to the way the equipment is configured: it has a very large opening that is flared at both ends, and the magnetic bore is only three feet in length, allowing for a very airy, relaxing environment. This procedure lasts about 30-60 minutes.
Open MRI Scans – High-Field Performance
The High-Field Performance Open MRI is a system that provides advanced magnetic resonance imaging capabilities with a number of unique features and benefits for guests.
An Open MRI scan is open on three sides, providing a very airy, roomy imaging experience. This machine is focused on providing the ultimate in comfort, using a wide-open design that offers panoramic views out all four sides. This open feeling helps create a relaxing environment. MRI Scans usually take about 30-60 minutes.
MRI Short Bore Scans – High-Field (1.5T)
MRI Short Bore scanners offer a comfortable MRI experience.
Short Bore Systems
Short bore systems are 50% shorter and 5% wider than conventional MRI setups. These dimensions allow for a very airy and roomy imaging experience.
High-Field 1.5T refers to the quality of the images provided. With a wide variety of coil options, 1.5T allows for the potential of better image quality across a variety of imaging applications (in comparison to the 3T) This unit has a well proven track record as being the best for high quality images.
MRI Shore Bore Scans tend to last 30-60 minutes.
MRI Open Bore Scans – High-Field (1.5T)
Open Bore Scans
The open bore MRI creates a wider opening, allowing for a much more comfortable MRI. It differs from the traditional MRI scanner in the size of the opening (“bore”). In a traditional bore, the opening is just slightly larger than the patient, which can tend to create a very restrictive and uncomfortable environment.
This system is combined with the very powerful 1.5T magnet, creating incredibly high quality images while maintaining a comfortable patient experience. Compared to the 3T, the 1.5T is well proven as being the best for high quality imaging.
MRI Open Bore Scans usually last between 30 and 60 minutes.
MRI Scans – High-Field (1.5T)
The High-Field 1.5T scanner provides the latest in advanced imaging technology.
This particular scanner is considered the industry standard, and is valuable for imaging all parts of the body.
This traditional MRI machine with the incredibly powerful High-Field 1.5T magnet takes about 30 to 60 minutes from start to finish.
The MRCP scan (magnetic resonance cholangiopancreatography) is a special form of MRI, focused on attaining images of the hepatobiliary and pancreatic systems, including the gallbladder, liver, bile ducts, pancreas, and pancreatic duct.
This is an absolutely painless, non-invasive medical test used to help diagnose abdominal pain, or to evaluate pancreatitis to detect the underlying cause. It also aids in the examination of diseases of the liver, gallbladder, bile ducts, pancreas, and pancreatic duct.
The actual MRCP exam takes about 10 minutes, but it is most often performed with a standard MRI of the abdomen, which may last approximately 30 minutes. In most cases, the entire examination is completed within 45 minutes total.
MRI Spectroscopy is a completely noninvasive technique used to characterize the biochemistry of tumors, infarcts and other pathology.
An MRI Spectroscopy is often done to diagnose certain metabolic disorders, including those affecting the brain. It can help determine specifics of a tumor, such as tumor aggressiveness, or tumor metabolism.
The MRI Spectroscopy provides additional information on chemicals present in the body’s cells, and may be performed during your MRI exam, while adding only approximately 15 minutes to the exam time.
What do I do if I am pregnant, is MRI safe?
Currently we scan pregnant patients only when it is considered medically beneficial. Your referring physician and an MRI Board Certified Radiologist will consult with one another and will sign consent forms deeming the MRI as a medically necessary procedure. Your doctor will then discuss the risks and benefits, and you will be asked to sign a consent form at the time of your appointment. The Radiologist will be available to discuss your exam and the risks and benefits of the procedure with you at the time of your appointment if you would desire.
What should I wear to my MRI appointment?
Typically street clothes are fine. A comfortable, loose fitting sweat suit or jogging outfit would be acceptable as well. For females, if we are scanning your spine, neck, chest or abdomen we will ask you to remove your bra. A sports bra contains no metal and would not need to be removed prior to scanning. We do have hospital gowns and robes, as well as scrub suits that we can have you change into, if necessary. We will ask you to place any loose metal from your pockets into a lockable storage area.
Your technologist will ask you to remove anything metallic, such as dentures, hearing aids, jewelry, hairpins or articles of clothing that may contain metal, such as underwire bras. These items, along with your purse, wallet, keys, pagers, cell phones or other personal items will be secured in a locker during your exam. You may be asked to change into scrubs, but if you are wearing sweats or clothing without any sort of metal, you may not be asked to change.
What is MRI?
MRI or Magnetic Resonance Imaging is a way to look inside your body without the use of X-rays. It is completely painless. MRI can allow your doctor to see certain types of tissue and can provide very important information about the brain, spine, joints and internal organs. MRI can allow your physician the opportunity for early detection of disease or injuries so proper treatment may be started as soon as possible.
How does MRI work?
Your body is composed of atoms. Water or hydrogen atoms make up 95% of the human body. Usually the hydrogen atoms within the body spin at random. When you have an MRI, you are placed in a strong magnetic field that is up to 8,000 times stronger than that of the earth, which causes these atoms to realign and spin all in the same direction. Like CT, MRI acquires images that are a "slice" of anatomy. Using the magnetic fields and radio waves, remarkably detailed cross-sectional images of the body can be obtained. A computer processes these images to produce detailed pictures of the anatomy.
Can anyone have an MRI?
Because some metals interfere with the function of the MRI equipment, certain patients are not able to have an MRI exam. The following equipment or conditions may create problems with an MRI. Please call with concerns about any of the following metals in your body.
- A pacemaker or pacing wires
- Metal fragments in one or both eyes
- Inner ear implants
- Cerebral anuerysm clips
- Implanted neuro stimulator
- Tens unit
- Certain metal implants
How long does it take?
The exam usually takes between 30 and 60 minutes. If your doctor orders your MRI exam with contrast, the exam may take longer to complete.
What is contrast?
In some cases, your doctor may order your test with contrast. This is a fluid that is injected into a vein (usually in your arm). This helps to make certain details on the exam clearer and is routine for certain MRI exams.
What will happen during the MRI exam?
You will be asked to lie down on the examination table on your back. The table will slide smoothly into the opening, and you will be positioned either head first or feet first, depending on the type of exam. Once the exam begins, it is important that you are as still as possible. You will hear "knocking" and "banging" noises, and the hum of the machine. This is all normal and you will be able to talk to the technologist during your procedure. You will be able to listen to the radio, or you may bring a favorite CD, or choose one at our facility.
What if I feel anxious or claustrophobic?
One of the first things we recommend to anyone who thinks they might feel anxious or claustrophobic during an exam is an advanced trip to our facility to actually look at the scanner. We often find that once patients see how wide the opening is and how short the scanner is, their anxiety is eliminated. Remember, MRI scanners have changed dramatically over the last 10 years, and are no longer made with such small, restrictive openings and long "tubes" or "tunnels".
Our technologists are very skilled at helping you feel relaxed and comfortable during your exam. It often helps to listen to music during your exam. You may have a family member in the room with you if you desire. In very rare instances, a patient may require sedation, which must be scheduled ahead.
