• Preparing for Your Exam

    • Take nothing by mouth four hours before your exam.
    • All meals 24 hours before your exam must be fat-free.

    1. Obtain two 10 oz. bottles of Citrate of Magnesia. Please consult your physician if you have kidney, liver or heart disease to be sure this prep is safe for you. Take any medications that you normally do unless directed by your physician.
    2. On the day before the exam, drink only liquids for breakfast, lunch and dinner. No food is allowed.
    3. At 4 p.m., drink one 10 oz. bottle of Magnesium Citrate. This may be diluted with a clear lemon/lime soda or juice. Follow with additional clear fluids.
    4. Drink at least five 8 oz.portions of a clear liquid.
    5. At 8 p.m., drink the second bottle of Magnesium Citrate.
    6. Drink at least five 8 oz.portions of clear liquid before retiring.
    7. On the day of the exam, do not eat or drink prior to the exam. Normal medications may be taken with a few sips of water.
      CLEAR LIQUIDS ALLOWED: Water, clear fruit juices (apple, white grape), Gatorade, bouillon, Jello, coffee or tea without milk (no more than 8 oz.).

    Please wear a two-piece outfit for comfort.

    If you are 59 years old or older, have kidney disease (other than stones), or diabetes, a BUN and Creatinine blood test must be performed and the results reviewed by your referring physician before the CT exam. If you had a normal BUN and Creatinine drawn within the last three months, then those results are acceptable unless those results were abnormal in which case the blood test should be repeated.

    Patients in chronic renal failure undergoing regular dialysis will not need BUN/Creatinine. They will need to be dialyzed within 24 hours of CT with IV contrast CT examinations.

    If you have a history of prior allergic reaction to iodinated contrast (x-ray dye), a history of prior anaphylaxis, or a history of asthma that requires daily medication, you should receive our standard pre-medication - you can get a referral for this medication from any AADI site.

    • Do not eat or drink after midnight the night before your exam.
    • Take any medication you normally do unless your doctor tells you differently.

    • Do not use colognes, perfumes, deodorants or body powders before your exam.
    • Please wear a two-piece outfit for comfort.

    • Finish drinking 32 ounces of clear liquids (no carbonated drinks) one hour before the start of your appointment time.
    • Do not empty your bladder before your exam.

    DO NOT eat or drink (except water) for at least 4 hours before your scan. If you take medication, take it with plain water. Longer fasting and drinking plenty of water improves scan quality.

    The day before your exam avoid sugar, sweets like cookies, ice cream, fruit and soda, and do not eat shellfish such as mussels or oysters. It is recommended to eat protein-rich foods such as chicken, nuts, eggs, cheese.

    Diabetics should NOT take insulin or oral anti-hyperglycemic for at least 4 hours prior to your appointment. Blood sugar levels will be checked and the procedure may have to be rescheduled for blood sugar >200.

    DO NOT perform any strenuous activity for at least 24 hours before your appointment. This includes exercise in any form.

    Patients who have primary cancers that often metastasize to the bone (i.e. lung, breast, prostate) or patients who may have a recurrence of their previously diagnosed cancer are the best candidates for the 18F NaF PET/CT bone scans

    Benefits of using 18F NaF for bone scanning include:

    • Bone uptake of 18F NaF is two times higher than for 99mTc medronate
    • Rapid clearance and low protein binding
    • High bone to background ratios
    • Minimal patient prep, including no restrictions on food intake, medication or activity
    • Shorter study times, typically less than 1 hour
    • Shorter radiation exposure period

    • Take nothing by mouth after midnight.
    • Take two Dulcolax suppositories two hours before your exam.

    Take a Fleet enema one hour before your exam.

    • Take nothing by mouth after midnight.
    • Do not smoke or chew gum.
    • For children under age 2, bring an empty bottle. Children should take nothing by mouth four hours before the exam.

  • * These tests must be scheduled before any barium procedure.
