MRI

Preparing for any type of MRI

  • Wear clothing that is comfortable and free of metal
  • Remove all earrings, body piercings, watches and other jewelry and store in a secure location
  • Most joint replacements, surgical mesh and stents are MRI compatible
  • Pacemakers, defibrillators, and brain aneurysm clips are NOT MRI compatible
  • Notify us of any of the following prior to your arrival at the facility:
    • Pregnancy (or possible pregnancy)
    • Implanted drug infusion device
    • Foreign metal objects, especially if in or near the eye (like shrapnel or bullets)
    • Permanent cosmetics or tattoos
    • Dentures, teeth or dental implants with magnetic keepers
    • Orthodontic braces
    • Any implants that involve magnets
    • Medication patch (i.e., transdermal patch) that contains metal foil

    Note:

    Servant technologists are very knowledgeable about what types of implanted devices, braces and internal wires will interfere with an MRI or pose a danger to your health. Please contact the Servant location where your scan is scheduled and discuss all such issues with a member of our staff prior to your arrival at the facility.

    If your scan requires contrast see these additional notes:

    • Stay very hydrated up to the time of your exam
    • The following criteria necessitate blood work with BUN/Creatinine results within 45 days of your scan:
      • Over age 65
      • History of hypertension, diabetes, liver disease, chemotherapy

CT

Preparing for a CT with contrast:

All IV contrasted CT exams require patients to go without food or drink for 2 hours prior to your exam. Be sure to drink plenty of water up to 2 hours prior to your exam. The following criteria necessitate blood work with BUN/Creatinine results within 45 days of your scan:

  • Over age 65
  • History of hypertension, diabetes, liver disease, chemotherapy

Note:

To ensure patient safety, Servant policy regarding Metformin-based medication is to discontinue its use at the time of any CT exam with intravenous (IV) iodinated contrast and withhold the medication for 48 hours after the exam. If there is no history of renal disease and the pre-exam Creatinine is normal, Metformin may be restarted after 48 hours. If there is a history of renal disease or the Creatinine was elevated , kidney function must be re-evaluated with your physician, and found to have returned to baseline or normal before Metformin is restarted.

CT Abdomen/Pelvis with/without contrast:

Patients may take medications with a small amount of water. If your exam is for abdomen only: you will be required to go without food or drink for 2 to 4 hours prior to your exam. You will drink ¾ bottle of barium while filling out your paperwork and the remainder when technologist begins your exam. If exam is for abdomen and pelvis: you are to go without food or drink for 2 to 4 hours prior to exam. You will arrive at the facility one hour before your exam and drink one bottle of barium slowly for 30 minutes. (If you have already been given barium, drink the 1st bottle before your appointment and arrive 30 minutes early). At the center, 30 minutes before your exam, you will drink the 2nd bottle to ¼ full and finish the remainder before the exam starts.

CT Abdomen/Pelvis without contrast:

Follow the same instructions as CT Abdomen/Pelvis with/without contrast (above). You will be given oral contrast only; no IV contrast will be administered.

CT Abdomen/Pelvis kidney stone protocol:

No prep or barium needed.


Ultrasound

Appropriate preparation for an ultrasound is essential to ensuring a successful result. Following are the required preps for our most common exams:

Abdomen ultrasound (including liver, pancreas, aorta, kidneys, spleen and gallbladder ultrasounds) require the patient to go without food or water for 6 hours prior to the exam. Patients may take medications with a small amount of water.

Aorta ultrasounds require the patient to go without food or water for a minimum of 6 hours prior to the exam. Patients may take medications with a small amount of water.

Kidney and Bladder ultrasound (renal) requires that the patient drink and retain a full 20 ounces of water one hour prior to exam. You must FINISH the water one hour prior to the exam so your bladder is full.

Pelvic ultrasounds require a full bladder and the patient must drink and retain a full 32 ounces of water one hour prior to the exam and hold their bladder. You must FINISH the water one hour prior to the exam so your bladder is full. If the Pelvic exam being done in combination with abdominal/liver/gallbladder ultrasound, you must also go without food or other drinks for 6 hours prior to the scan.

Obstetric ultrasounds to examine fetal anatomy, uterus and ovaries require the patient to drink a full 32 ounces of water one hour prior to the exam. You must FINISH the water one hour prior to the exam so your bladder is full. (For our cosmetic 4D information click HERE.)
