Magnetic Resonance Imaging (MRI)

WHAT IS AN MRI?
Magnetic Resonance Imaging (MRI) is an amazing technology that creates images for a radiologist to interpret from the water in your body. Giant magnets allow your body to receive radio waves and “echo” them back. A computer uses the information within the echoes that bounce back from your body to create images.

The images created are unique to a patient, depicting his or her anatomy and any disease that may be present. The whole process is safe and painless. Some patients are so comfortable inside the magnet that they actually fall asleep while this advanced imaging takes place.

Short-Bore MRI
The radiologist may administer Valium, a relaxing medication, for patients experiencing anxiety or claustrophobia so that the examination will be a more acceptable experience. Family members or friends who can drive the patient home after the exam must accompany patients who receive intravenous Valium. These patients are advised not to drive or operate dangerous equipment for the remainder of the day.

ARE THERE ANY RISKS?
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, so it is important for you to tell us if any of the following apply to you or someone accompanying you into the exam room:

  • cardiac pacemaker, defibrillator (AISCD) or artificial heart valve
  • metal plate, pin or other metallic implant
  • intrauterine device, such as Copper-7 IUD
  • insulin pump or other infusion pump
  • aneurysm clips
  • previous gunshot wound
  • middle/inner ear implant
  • ever been a metal worker (had metal in eye)
  • permanent (tattoo) eye-liner
  • pregnant *
  • artificial joints or metallic plates **

Any metallic substance on your person can affect the quality of the diagnostic images. It can also cause discomfort or injury to you when placed in the magnetic field, and may exclude you from the exam.

Also, be sure to tell us if you are pregnant.

* Pregnant patients should discuss the examination with the radiologist prior to the appointment/examination. Although there are no known side effects on the developing baby, it is recommended that a pregnant woman wait until the second trimester for MR imaging. There are some exceptions to this rule. Wake Radiology also feels that Gadolinium (contrast material) should not be injected in the setting of pregnancy, and thus pregnant patients will only have non-contrast MRIs.

** You can safely undergo MRI if you have orthopedic metallic hardware in your joints—such as a metallic plate or hip replacement. However, if the metal device is located close to the part of the body being examined, the images can be seriously degraded and useless.

WILL I NEED AN INJECTION?
In most cases an MRI exam does not require an injection. In some situations, however, a substance known as a contrast agent (Gadolinium) may be needed to enhance the ability of the MRI to see into your body. All contrast agents are FDA-approved and have an extremely low incidence of allergic reaction.

Note: Due to recent internationally accepted evidence that Gadolinium injection is linked to the onset of a rare disease known as Nephrogenic Systemic Fibrosis (NSF), Wake Radiology adheres to the nationally mandated guidelines set forth by the FDA. We will not utilize Gadolinium for MRI studies on  those patients who are at risk of NSF, such as those with documented severe chronic renal insufficiency or dialysis dependence. Those patients may safely have non-contrast MRIs if required clinically.

Very anxious patients may be given a sedative to help them relax and lie still during the exam. If you think you will require a sedative, please contact our office prior to appointment. You will need to bring someone to drive you home.

MRI of the Chest, Abdomen and Pelvis

mri5.pngSome of the latest advancements in imaging have occurred in MRI of the chest, abdomen, and pelvis, or “Body MRI.” Tumors sometimes can be classified as benign or malignant solely upon the information provided by MRI.

Body MRI examinations are the most specialized of all MRI applications. All examinations require the patient to lie on his/her back for 30–70 minutes, as still as possible. Many body examinations require the patient to hold his/her breath, repeatedly, for up to 30 seconds.

If you are scheduled for a MRI of the chest, abdomen, or pelvis and have difficulty holding your breath, you should alert the MRI staff upon your arrival. Sometimes, coaching before the examination is successful in achieving an adequate breath-hold for imaging. However, some patients will find that they cannot hold their breath adequately, and an alternate imaging method, such as CAT (CT) scan or ultrasound, may be recommended instead of MRI.

In some cases, the radiologist may determine that the patient must be injected with contrast. This is not a sign that something is wrong, but merely that additional information is required/requested. An examination that requires contrast is not an unpleasant experience. All contrast agents are FDA-approved and have an extremely low incidence of allergic reaction.

Some patients may be injected with Glucagon, a synthetic hormone that reduces motion within the bowel for about 60 minutes. Bowel motion can cause significant blurring of images in the abdomen and pelvis, potentially rendering images useless. The injection is given in the muscles of the arm, much like an immunization. This drug may induce hypoglycemia (low blood sugar) in patients approximately 90 minutes after injection, causing some nausea, dizziness, and trembling. Because eating can prevent these symptoms nearly completely, patients are required to eat chocolate, or other form of sugar, prior to leaving the facility. Patients are also instructed to eat a meal soon after the examination. Diabetics will typically not be given this injection, so please inform the staff if you have this condition.

Patient Preparation: Only patients undergoing MR examination of the gallbladder will be asked to not eat prior to imaging. No special preparation is required for other body examinations.

MRI of the Brain and Spine

mri10.pngAlmost all imaging of brain and spine involves the patient lying on his/her back for 30–60 minutes. In some cases, the radiologist may determine that the patient must be injected with contrast. This is not a sign that something is wrong, but merely that additional information is required/requested. An examination that requires contrast is not an unpleasant experience. The contrast material has an extremely low incidence of allergic reaction, and most patients do not even notice the injection.

Note: Due to recent internationally accepted evidence that Gadolinium injection is linked to the onset of a rare disease known as Nephrogenic Systemic Fibrosis (NSF), Wake Radiology adheres to the nationally mandated guidelines set forth by the FDA. We will not utilize Gadolinium for MRI studies on  those patients who are at risk of NSF, such as those with documented severe chronic renal insufficiency or dialysis dependence. Those patients may safely have non-contrast MRIs if required clinically.

Patient Preparation: No special preparation is required for these examinations.

MRI of the Bones and Joints

mri16.pngAlmost all imaging of bones or joints involves the patient lying on his/her back for 30–60 minutes. Occasionally, other positions are required to image small joints or special areas. In some cases, the radiologist may determine that the patient must be injected with contrast. This is not a sign that something is wrong, but merely that additional information is required/requested. An examination that requires contrast is not an unpleasant experience. The contrast material has an extremely low incidence of allergic reaction, and most patients do not even notice the injection.

Some special types of joint imaging require “arthrograms,” in which the patient is injected with contrast material inside the joint prior to MR imaging. Patients having these examinations will be instructed to arrive earlier than usual, so that a specially trained musculoskeletal radiologists may be present to administer the contrast into the joint.

Patient Preparation: No special preparation is required for these examinations.

MRI of the Blood Vessels (MRA, or MR Angiography)

mri22.pngWhen physicians need to see blood vessels, they create images called “angiograms.” Typical angiograms require admission to a hospital for the procedure, but MR angiograms can be performed without risk or hospitalization, in 30–70 minutes depending upon the body part to be imaged.

Patients undergoing MR angiography of any part of the body except the head will receive an injection of contrast material in the vein of an arm. In some cases, a second contrast injection may be required for some parts of the body. An examination that requires contrast is not an unpleasant experience. The contrast material has an extremely low incidence of allergic reaction, and most patients do not even notice the injection. MR angiography of the head (Circle of Willis, COW MRA) can be performed without a contrast injection.

Because very large amounts of data are created during these studies, they can easily have hundreds of images that require hours of manipulation to interpret. Referring physicians will be notified of results as soon as is possible.

Patient Preparation: No special preparation is required for these examinations.

 

Your Fears About The MRI Experience

Many patients are frightened by their physician’s recommendation to have an MRI. Most of the time, this is related to fear of claustrophobia or panic attacks. People have read or heard stories in the news, or from friends, about how having an MRI can feel like “being put into a coffin.” We at Wake Radiology wish to reassure you that this will not be the case at our facilities.

mri28.png

Although many patients fear getting into the magnet, or suddenly find that they are afraid once they see the magnet, we have found that almost all patients can successfully have an MRI at Wake Radiology when we administer medication on site.

That’s right — on site. We will provide the medication that you will need to get through the MRI examination without a problem. We do this by administering a small amount of Valium just before the examination.

After you arrive, at your request, we will place a small IV (intravenous) line into your vein, and through that we will administer a small amount of Valium. This will relax you for the exam, making it possible for you to easily manage your own stress or anxiety. We will not “put you to sleep,” but rather will relax you thoroughly for the duration of the examination.

Please note that if we give you Valium at our facility, you will need to have someone drive you home. Although you will feel nearly normal by the time the MRI is concluded, you will still be subtly affected by the medication, and cannot drive safely. Also, you should take the next few hours to relax, to allow the medication to wear off naturally.
