Patient Preparations

Blood work requirements for CT with IV contrast

Creatinine labs are needed for all patients regardless of age who are diabetic within two weeks of the exam, and for patients greater than 65 years old within six weeks of the exam.

Blood work requirements for MRI with IV contrast

Creatinine labs are needed for all patients regardless of age who are diabetic within two weeks of the exam, and for patients greater than 75 years old within six weeks of the exam.

Diabetic/renal-compromised patients having CT or MRI exam with IV contrast

Please be assured these are recommendations only. If you would like to speak to one of our radiologists for the best contrast guidelines for your patient, please call us directly. The ACR recommends that patients taking Metformin be classified into one of two categories based on the patient’s renal function (as measured by GFR).

1. Based on the ACR recommendations, patients who are taking Metformin and are non-renal compromised, i.e. with normal Creatinine level, can safely take their Metformin, without any restriction before or after the contrast injection.

2. In patients taking Metformin who are known to have acute kidney injury or severe chronic kidney disease (stage IV or stage V), the contrast will not be administered unless the patient is scheduled for dialysis the next day or within 24 hours. In this case, the Metformin should be temporarily discontinued at the time of the procedure and be withheld for 48 hours subsequent to the procedure and reinstituted thereafter.

No stimulants, decongestants, caffeine, or erectile dysfunction medication 48 hours prior to the exam. No allergies to iodinated contrast. A beta-blocker may be required.

Preparing for Your PET Scan at DCA: Medication and Diet

Patients are to arrive one hour and 30 minutes prior to scan time. This is MANDATORY. No exercise 24 hours before the exam; this includes any strenuous activity. Continue to take all your medications as prescribed, EXCEPT for your insulin medication. Do not take your insulin the morning of your test, but bring it with you.

Non-diabetic patients:

  • No eating or drinking four hours before the scan. You may have water during the four hours.
  • NO CANDY, GUM, FLAVORED WATER, SUGAR SUBSTITUTES, or ANYTHING WITH SUGAR, AFTER 3:00 pm the DAY BEFORE THE EXAM.
  • We recommend a high-protein, very low-carbohydrate, and no-sugar diet:
    • Dinner: Steak, baked chicken, fish, cheese, asparagus, broccoli, mushrooms. No pasta, potatoes, rice or bread.
    • Breakfast: Eggs (no toast or jelly), bacon, sausage. No breakfast should be eaten if you have an appointment before noon.

Diabetic patients:

  • The patient’s blood sugar needs to be 180 or lower. The insulin medication does not affect the exam, it’s the blood sugar levels.
  • If you feel it is necessary to take your insulin in the morning, do so with NO CARBS or SUGARS. Only protein as above, four hours before the exam.

What to bring with you and what to wear:

  • Bring with you or have your physician fax:
    • Your current insurance card(s)
    • Previous CT scans, X-rays, and prior PET exams
    • Medical history and current medications
    • Pathology reports
  • Wear warm, comfortable clothes. The exam room can be cool.
  • Avoid clothes with heavy buckles or metal components

What to expect during your PET scan:

  • A technologist will insert a small IV into your arm.
  • A small amount of FDG (a form of glucose) will be injected through the IV. This is painless.
  • You will rest quietly for 30 to 60 minutes in an ambient/dimly lit room without any audible or visual stimulation (e.g., cell phone, iPad, etc.) to allow for proper distribution of the FDG throughout your body.
  • Your scan will take approximately 25 minutes.

After your exam:

  • You may resume a normal diet, exercise, and medications.
  • As a precautionary measure, avoid getting close to an infant or pregnant woman (within six feet) for a minimum of eight hours after the exam.
  • Your doctor will contact you with your results.
