    What is an MRI?

    An MRI is an imaging technique that produces detailed pictures of internal organs and tissues. The images are created through the use of magnetic fields and radio waves. For some procedures a contrast agent (Gadolinium) is used to increase the detail of the images.

    Can anyone have an MRI scan? Are there any risks involved with having an MRI?

    Almost anyone can have an MRI. Although MRI is a non-invasive procedure that does not use any X-Ray radiation, it does require the use of a high strength magnetic field. People with pacemakers cannot undergo a MRI scan, also other metallic implants, aneurysm clips, bullet fragments and all prosthetics will need to be checked before a person with these would be scanned. Some tattoos and permanent eyeliner may be heated during a scan. Our staff will go over any of these issues with you before your test. There is no weight limit.

    Can someone who is pregnant undergo an MRI scan?

    MRI is generally avoided in the first 12 weeks of pregnancy. If after this time all physicians involved in your care and our radiologist determine it is absolutely medically necessary and is beneficial, then you may have an MRI.

    How can I prepare for an MRI procedure?

    It is best to wear loose comfortable clothing with no metal. You may be asked to change into a hospital gown for some procedures. It is best to wear no jewelry, as you will need to remove it for the test. Please keep makeup to a minimum, some products contain metallic flakes that could cause a patients skin to heat up and also cause artifacts that will degrade the images.

    Can I eat before my exam?

    Yes. The only MRI procedure that has a restriction is a MRCP exam. This is a special exam of your abdomen that requires you to not eat or drink for 6 hours before your test.

    How long does an MRI take?

    Depending on the test you are having done, anywhere from 30 minutes to 1 hour.

    What will happen during the test?

    MRI is a very noisy test. Normally ear protection is given to help block some of the noise. You may feel the table vibrate and move occasionally during the test. It is very important to hold extremely still for the entire test. If you are claustrophobic or in severe pain you may want to ask your referring physician about medication to help get you through the test.

    PET-CT Scan Overview

    What is Positron Emission Tomography (PET)? 

    Positron emission tomography (PET) is a specialized radiology procedure used to examine various body tissues to identify certain conditions or follow the progress of the treatment of certain conditions. While PET scan is most commonly used in the fields of neurology, oncology, and cardiology, applications in other fields are currently being studied. Through state of the art technology, positron emission tomography (PET) and computed tomography (CT) are combined into one procedure, PET/CT, to image the whole body. The technology is used primarily to assess cancers, such as lung, colorectal, esophagus, lymphoma, breast, and melanoma.

    How does PET work?

    PET scans work by using a scanning device (a machine with a large hole at its center) to detect positrons (subatomic particles) emitted by a radionuclide in the organ or tissue being examined.

    PET scans use chemical substances such as glucose, carbon, or oxygen that are used naturally by the particular organ or tissue during its metabolic process. A radioactive substance is attached to the chemical required for the specific tests. For example, in PET scans of the brain, a radioactive substance is applied to glucose to create a radionuclide called fluorodeoxyglucose (FDG), because the brain uses glucose for its metabolism. FDG is widely used in PET scanning.

    Other substances may be used for PET scanning, depending on the purpose of the scan. If blood flow and perfusion of an organ or tissue is of interest, the radionuclide may be a type of radioactive oxygen, carbon, nitrogen, or gallium.

    The radionuclide is administered into a vein through an IV line and allowed to circulate the specific organ before the image can be taken. Next, the PET scanner slowly moves over the part of the body being examined. Positrons are emitted by the breakdown of the radionuclide. Gamma rays are created during the emission of positrons, and the scanner then detects the gamma rays. A computer analyzes the gamma rays and uses the information to create an image map of the organ or tissue being studied. The amount of the radionuclide collected in the tissue affects how brightly the tissue appears on the image, and indicates the level of organ or tissue function.

    Reasons for the Procedure 

    In general, PET scans may be used to evaluate organs and/or tissues for the presence of disease or other conditions. PET may also be used to evaluate the function of organs such as the heart or brain. Another use of PET scans is in the evaluation of the treatment of cancer.

    More specific reasons for PET scans include, but are not limited to, the following:

    • To diagnose dementias such as Alzheimer's disease, as well as other neurological conditions such as Parkinson's disease (a progressive disease of the nervous system in which a fine tremor, muscle weakness, and a peculiar type of gait are seen), Huntington's disease (a hereditary disease of the nervous system which causes increasing dementia, bizarre involuntary movements, and abnormal posture), epilepsy (a brain disorder involving recurrent seizures), and cerebrovascular accident (stroke)
    • To locate the specific surgical site prior to surgical procedures of the brain
    • To evaluate the brain after trauma to detect hematoma (blood clot), bleeding, and/or perfusion (blood and oxygen flow) of the brain tissue
    • To detect the spread of cancer to other parts of the body from the original cancer site
    • To evaluate the effectiveness of cancer treatment
    • To evaluate the perfusion to the myocardium (heart muscle) as an aid in determining the usefulness of a therapeutic procedure to improve blood flow to the myocardium
    • To further identify lung lesions or masses detected on chest x-ray and/or chest CT
    • To assist in the management and treatment of lung cancer by staging lesions and following the progress of lesions after treatment
    • To detect recurrence of tumors earlier than with other diagnostic modalities

    There may be other reasons for your physician to recommend a PET scan.

    Before the Procedure 

    • Your physician will explain the procedure and offer you the opportunity to ask any questions that you might have about the procedure.
    • You will be asked to sign a consent form that gives your permission to do the procedure. Read the form carefully and ask questions if something is not clear.
    • Fasting for a certain period of time prior to the procedure is required, usually for at least four hours. Your physician will give you special instructions ahead of time as to the number of hours you are to withhold food and drink. Your physician will also inform you as to the use of medications prior to the PET scan.
    • Notify your physician if you are pregnant, suspect you may be pregnant, or nursing.
    • Notify your physician of all medications (prescribed and over-the-counter) and herbal supplements that you are taking.
    • You should not consume any caffeine or alcohol, or use tobacco, for at least 24 hours prior to the procedure.
    • If you are a diabetic who uses insulin, you may be instructed to take your pre-procedure insulin dose with a meal three to four hours prior to the procedure. Your physician will give you specific instructions based on your individual situation. Also, a fasting blood sugar test may be obtained prior to the procedure. If your blood sugar is elevated, you may be given insulin to lower the blood sugar.
    • Based upon your medical condition, your physician may request other specific preparation.

    During the Procedure 

    Generally, a PET scan follows this process:

    • You will be asked to remove any clothing, jewelry, or other objects that may interfere with the scan.
    • If you are asked to remove clothing, you will be given a gown to wear.
    • You will be asked to empty your bladder prior to the start of the procedure.
    • One or two IV lines will be started in the hand or arm for injection of the radionuclide.
    • Certain types of scans of the abdomen or pelvis may require that a urinary catheter be inserted into the bladder to drain urine during the procedure.
    • In some cases, an initial scan may be performed prior to the injection of the radionuclide, depending on the type of study being done. You will be positioned on a padded table inside the scanner.
    • The radionuclide will be injected into your vein. The radionuclide will need to concentrate in the organ or tissue for a least 60 minutes. You will remain sitting still at the facility during this time.  The technologist will have you relax in a reclining chair in a quiet area while the radionuclide circulates.  You will have to remain fairly still so the radion does not concentrate in the tissue of the muscles. You will not be hazardous to other people, as the radionuclide emits less radiation than a standard x-ray.
    • After the radionuclide has been absorbed for the appropriate length of time, the scan will begin. The scanner will move slowly over the body part being studied.
    • When the scan has been completed, the IV line will be removed. If a urinary catheter has been inserted, it will be removed.

    While the PET scan itself causes no pain, having to lie still for the length of the procedure might cause some discomfort or pain, particularly in the case of a recent injury or invasive procedure such as surgery. The technologist will use all possible comfort measures and complete the procedure as quickly as possible to minimize any discomfort or pain.

    After the Procedure 

    You should move slowly when getting up from the scanner table to avoid any dizziness or lightheadedness from lying flat for the length of the procedure.

    You will be instructed to drink plenty of fluids and empty your bladder frequently for 24 to 48 hours after the test to help flush the remaining radionuclide from your body.

    The IV site will be checked for any signs of redness or swelling. If you notice any pain, redness, and/or swelling at the IV site after you return home following your procedure, you should notify your physician as this may indicate an infection or other type of reaction.

    Your physician may give you additional or alternate instructions after the procedure, depending on your particular situation.
