What is an MRI?

MRI, Magnetic Resonance Imaging, is a method used by physicians to look inside the body to obtain diagnostic information. Through advanced technology, MRI produces images of the anatomy without the use of radiation, as in X-ray or CT scanning. MRI utilizes the physical properties of magnetic fields, radio waves and computers to generate images of the soft tissue within the body on all three planes or at an angle. This technique is now commonly used as a primary diagnostic tool. It can help provide a quick and more accurate diagnosis for your physician, who may be able to reduce the need for exploratory surgery and other diagnostic procedures that might involve associated risk. MRI is a non-invasive procedure and there are no known side- or after-effects. The procedure is painless; in fact, you won't see or feel anything. A faint knocking sound will be heard. This is simply the imaging process in operation. The procedure is used for all parts of the body and is effective in the clinical evaluation of the following conditions:

• Brain Disorders
  
• Traumatic Injuries
  
• Eye Abnormalities
  
• Spine Diseases
  
• Tumor Detection
  
• Liver and Other Abdominal Diseases
  
• Knee and Shoulder Injuries
  
• Musculoskeletal Disorders
  
• Facial/Neck Abnormalities
  
• Infection
  
• Cardiac Malformations
  
• Blood Flow and Vessel Disorders

What does an MRI see?

While X-rays are best for showing bones, MRI creates pictures that can show differences between healthy and unhealthy tissue. Doctors use MRI to examine soft tissues such as organs, muscle, cartilage, ligaments, and tendons. MRI is helpful when looking at the brain, spinal column, breast, abdomen, pelvic region, and joints, including the knee and elbow.

What is the difference between High Field Magnetic Resonance Imaging (MRI) and an Open Mid-Field MRI?

Our center is proud to offer you the latest in diagnostic technology and the utmost in patient comfort. We are equipped with both a High Field MRI and an Open Mid-Field MRI. Unlike other devices used in radiology, MRI uses no radiation. The magnet in the housing of the scanner creates a magnetic field oriented down the center of the magnet.

High Field MRI

The High Field scanner is shaped like a tunnel that is open at both ends. Patients are provided with reflective prism glasses to allow a view outside of the scanner (also called a magnet). You will position yourself within the magnetic field by lying on a table that stretches through the center of the opening of the magnet. The strength of the magnetic field is measured in units called Gauss or Tesla: 10,000 Gauss equals 1 Tesla. The earth's magnetic field is approximately 0.6 Gauss. This scanner's speed is faster and it's resolution is stronger than an Open Mid-field MRI, which is why your doctor may prefer it for your exam.

Open Mid-Field MRI

The Open Mid-Field MRI has a 0.3 Tesla. There is no tunnel to slide into; rather the magnet is open on four sides. It is ideal for large patients as well as those who feel claustrophobic. If you think that you may become anxious during the exam, please let us know before your appointment. We can provide an oral sedative. Still, most claustrophobic patients are able to undergo the scan without such medication.

Is there anyone who cannot have an MRI?

If you are pregnant, please notify your physician. Also, patients with the following should not have an MRI:

• Cardiac Pacemaker
  
• Aneurysm clips in the brain
  
• Foreign metal objects in the eye

While people of all ages have had MRIs, potential harmful effects are associated with all metallic objects in a magnetic field. Therefore, you should check with your physician or MRI technologist if you have had brain, ear, eye or other surgeries or any of the following:

• Neuro-stimulator (Tens-units)
  
• Surgical Staples
  
• Implanted Drug Infusion Devices
  
• Shrapnel or Bullet Wounds

What should I expect during the exam?

The procedure typically lasts between 30 to 45 minutes, depending on the type of information required by your physician. All that is required of you is to be as still as possible. The technologist, who sits just outside the exam room, is able to see you the entire time. However an intercom system is built into the magnet so that the technologist can quickly enter if you need anything at all. Additionally, patients may bring CDs or tapes or choose from our selection.

When will I receive my results?

If your physician's office is in the San Gabriel Valley area, the office will receive your results within 24 hours. Other offices will receive results within 2 to 3 working days.

Do I have to prepare for my exam?

No special preparation is required prior to an MRI exam. You may eat normally and go about your daily routine. Continue to take any medication prescribed by your doctor unless otherwise directed by your physician. Because of the magnetic field, you will be asked to leave the following items in a safe place outside the scan room:

• Coins
  
• Jewelry
  
• Watches
  
• Glasses
  
• Credit Cards
  
• Keys
  
• Hair Pins
  
• Other Metal Objects

You may also be asked to remove makeup or dentures and wear a hospital gown to avoid magnetic interference from belt buckles or zippers. Once you are situated on the table, make sure you are comfortable so that it is easy to keep still. Breathe normally and relax. The only thing you will notice is a faint knocking sound which represents the changes in magnetic field. Once the exam is over, the technologist will assist you out of the scan room.
