  • Mammogram

    How should I prepare for a mammogram?

    Do not wear deodorant or anti-perspirant on the day of your mammogram because they may interfere with the mammographic images.

    Breast biopsy

    How should I prepare for an ultrasound guided breast biopsy?

    In order to reduce the risk of bleeding during the procedure, we recommend that patients not take any aspirin product for 2 days prior to the procedure and not take any ibuprofen product (such as Advil or Motrin) for 24 hours prior to the procedure. If you are on a prescription blood thinning medication such as Coumadin or have a medical condition that requires you to take aspirin, please consult your physician prior to scheduling this exam.

  • CT scan:

    For a scan of the head (brain), neck, chest, arms and legs:

    • Do not eat or drink for four hours before your exam.
    • Do not have any liquid or solid food for four hours prior to your scheduled appointment time, but do take your prescription medications with a sip of water.
    • Pick up one CT drink kit from the CT department on the day before your exam. (This drink will make it easier for the radiologist to see your intestines and not confuse them with abnormal structures.)

    Instructions for the CT contrast drink:

    • The kit contains two bottles of readi-cat contrast drink. This is pre-mixed and may taste better when refrigerated. Please shake well before using. Do not mix with any other substance or pour over ice.
    • Ninety minutes before your scheduled appointment time, drink one bottle.
    • Thirty minutes prior to your appointment time, drink 2/3 of the second bottle.
    • Immediately before the test you will be instructed by the technologist to drink the last third of a bottle.

    For a CT angiogram (to look at blood vessels, aortic aneurysms, renal transplant donors):

    • Do not eat or drink for two hours before your exam.
    • Do not drink the CT contrast drink

    • Stop taking aspirin or aspirin products (Bufferin, Excedrin, Ecotrin, etc.) For 7 days before the procedure.
    • If you take coumadin or warfarin (blood thinners), they should be stopped 4 days before the procedure and a blood test (prothrombin time) should be drawn 2 days before the procedure. These test results should be faxed to the CT section at 401-793-4431.
    • Stop taking anti-inflammatory medications (i.e., motrin (ibuprofen), indocin, Naprosyn, etc.) 7 days prior to the procedure. It is okay to take Tylenol (acetaminophen).
    • Important: If you take aspirin or blood thinners (i.e., coumadin) less than 4 days before the procedure, please call the CT scheduler at 401-793-4430 as the procedure will need to be rescheduled for a later date.
    • If your doctor ordered blood tests that were done outside of The Miriam Hospital, bring the results with you or have them faxed to our department at 401-793-4431.

  • Preparing for your MRI exam

    To avoid delays on the day of your MRI exam, please be sure to arrive 30 to 60 minutes prior to your MRI appointment to register. Time and place will be dependent on the study and facility; instructions will be given at the time of scheduling.

    If you are having an MRI of the abdomen or pelvis, please have nothing to eat or drink 4 hours prior to appointment time. If you must take oral medication, use a minimal amount of water.

    You'll be given separate instructions if you are receiving Anesthesia or Pediatric Sedation.
