Nuclear medicine imaging uses very small amounts of radioactive materials called radiopharmaceuticals to diagnose and treat disease. These radiopharmaceuticals, which are given orally or through an IV, are detected by special types of cameras that work with computers to provide very precise pictures about the area of the body being imaged. If your child’s doctor has ordered this test, you can make an appointment to have it performed at Wolfson Children’s Hospital.

NM CSF Leakage and Cisternogram Scan Preparation Guidelines:
  • Nothing to eat or drink 4 hours prior to the study.
  • Informed consent must be obtained prior to the lumbar puncture.
NM Gastric Emptying and Gastric Reflux Scan Preparation Guidelines:

  1. Patients LESS than 1 year old:

    Nothing to eat or drink for 4 hours prior to the scan.

    Please send a bottle with formula or breast milk (it can be thickened with cereal, if necessary). The patient will need to eat for the exam.

  2. Patients OVER 1 year old:

    Nothing to eat or drink for 6 hours prior to the exam.

    Please bring formula or baby food, or, if patient is old enough, either eggs or oatmeal, with 2 slices of bread and some butter. The patient will need to eat for the exam.

    Please call the department if patient won't eat eggs or oatmeal, or if you have any questions regarding the meal. Nuclear Medicine will try to come up with alternatives, if possible.

  3. For ALL Patients

    No Barium of any other type of radio-opaque oral contrast for 48 prior to exam. If patient had such contrast given in the last 48 hrs, a KUB will be needed to determine whether or not barium will impede the study.

    No stomach medications or anti-emetics for at least 12 hours prior to the exam. This includes things such as Phenergan, Zofran, Nexium, Protonix, Reglan, Erythromycin. These medications may slow gastric motility and can cause abnormal results.

    No Benadryl or Ativan, (given sometimes IV for nausea), as these will also adversely affect the results of the scan.

    For patients with NG Tubes a KUB will need to be performed just prior to the nuclear medicine procedure to ensure proper tube placement.

    NJ Tubes cannot be used for gastric procedures in nuclear medicine, as they bypass the stomach. If a patient has an NJ tube in place, the patient will have to eat P.O., or else the NJ tube shall have to be pulled up into the stomach for the gastric emptying scan, in which case a KUB will be needed to confirm.

NM Hepatobiliary Scan Preparation Guidelines:

Up to 6 months of age:

  • Nothing to eat or drink 4 hours prior to the study.

    6 months and up:

  • Nothing to eat or drink 6 hours prior to the study

    Infants under 1 year need to be on phenobarbital for at least 5 days prior to exam.

    Also, if patient is under 5 years old, recommend they arrive at least 1 hour prior to appointment to allow time for patient exam preparation and IV start.

  • NM Hepatobiliary w/Kinevac Preparation Guidelines:

    • Nothing to eat or drink 6 hours prior. If patient has been NPO for 24 hrs or longer, he or she may need to be pre-treated with Kinevac prior to the start of the scan.
    • No pain medication, particularly morphine, Demerol, Dilaudid 6 hr prior to exam.
    • No oral contrast 48 hours prior to exam. Otherwise, a KUB needs to be performed prior to exam, to make sure barium will not interfere with exam.
    NM I131 Thyroid - Total Body Preparation Guidelines:

    • NPO 4 hours before, and at least 1 hour after the administration of the radiopharmaceutical (radioactive pill).
    • NO IV contrast media (IVP, CT), 1-2 moths prior to exam.
    • NO OralContrast media (even non-ionic) for 6 weeks prior to exam
    • NO Thyroid Medications: Cytomel, Synthroid, Proloid, Levoxyn for 3 weeks.
    • NO iodine solution (SSKI, Lugols), Kelp, cough medicines or vitamins for 2 weeks prior.
    • No Tapazole, Perchlorate, Nitrates, Bromides or Adrenocorticosteroids for 1 week prior to the exam.
    • Should not be breast feeding.

    Thyroid related lab results should be available.

    NOTE: If the patient is unable to swallow a pill DO NOT SCHEDULE

    If the patient is under 5 years old, sedation is needed, and sedation prep guidelines will apply.

    NM Brain SPECT Preparation Guidelines:

    Patient needs to arrive 1 hour prior the start of the exam.

    Once the IV has been inserted, the room will me made dim and quiet. No cellphones, talking, or interacting with the patient during this time. This could alter the patient's blood flow to the brain, and affect the quality of the study in an adverse manner. Please be as quiet and still as possible.

    NM Renal Scan with Lasix or Captopril (NM Renal Function with Intervention Scan) Preparation Guidelines:

    Patient should arrive at least 90 minutes prior to exam, so they can go to POPS for IV start and administration of IV fluids prior to nuclear medicine exam.

    For Captopril exams ONLY:

    NO ACE Inhibitors for 48-72 hours prior to exam. This includes: Captopril (Capoten), Prinivil, Vasotec, Zestril and others. If in doubt, please call Nuclear Medicine at 202.8150.

    Nurse will also evaluate and record the patient's blood pressure every 15 minutes for 1 hour prior to starting the exam, so the total exam time will be a bit longer. Make sure the patient has obtained, filled and brought with them a prescription for oral Captopril from their doctor.
