Procedure Preparations

MRI

Pancreas or MRCP – Nothing by mouth for three hours prior to exam time. All other MRI exams – No prep necessary.

MRI uses strong magnets, so you’ll be asked to remove your watch, jewelry, and other metal objects. Some makeup also contains traces of metal, so you might have to remove that, too. Braces and fillings normally aren’t a problem.

X-Ray

There is no prep necessary for a plain film x-ray exam. You might be asked to remove your watch, jewelry, or garments with metal closures from the part of your body being imaged. Let the technologist know if you might be pregnant.

CT Scan

Your test may require that you be injected with contrast (an iodine contrast material that enhances the image). We need to know if you have any known history of previous reaction to iodine contrast.

Let the technologist know if you might be pregnant.

CT Abdomen and/or CT Pelvis – It may be necessary to pick up a prep kit at least two days before your exam.

Pregnancy or Pelvic Ultrasound

You are being prepared for an ultrasound exam that requires you to have a full bladder. To ensure best results, please follow these instructions: Two hours before exam time, empty your bladder. Immediately after your last urination, begin drinking 1.5 quarts of liquid (no milk or dairy products) – drink a cup every fifteen minutes. It takes two hours to fill the bladders, so do not wait to start drinking just before your exam time. Your bladder will feel very uncomfortable – please remember not to urinate until after your ultrasound exam is completed! If you have concerns about your bladder, please tell your ultrasound tech before the start of your exam. Please remember not to urinate until after your ultrasound exam is completed!

Nuclear Medicine

You may be told not to eat, drink, or take certain medications before your scan. You will be asked to remove metallic objects, such as jewelry. You will be given a small amount of radioactive tracer. It is most often injected, but it may be swallowed. You might need to wait a few minutes or hours before having your scan in order for the tracer to concentrate in the part of your body being studied. In the case where you will be imaged several hours later, you may leave and return later that day.

PET (Positron Emission Tomography)/CT Fusion Scanning

Do not eat or drink anything except water for four to six hours before your exam because it could interfere with the results. Do not even chew gum, eat candy, or use cough drops. If you take medications, drink only enough plain water to swallow them. If you’ve been advised not to take your medications on an empty stomach, eat nothing more than a few soda crackers within four to six hours of your exam. If you are diabetic, let us know ahead of time so that we can work with your physician to determine the safest possible way for you to prepare for your exam.

Mammogram

Please do not wear any perfumes, lotions, creams, deodorants or powders under your arms or breasts. If your most recent prior mammogram was performed elsewhere, you will need to obtain those films and reports prior to your exam to have available for comparison.

Bone Density (DEXA Scan)

Do not take calcium supplements 24 hours prior to your exam; some vitamins may contain calcium also.

Small Bowel Series

Barium Enema

Examples of clear liquids include coffee, tea, soda, water, gelatin, broth, hard candy, sports drinks (such as Gatorade), popsicles, and juice without pulp. You must come in to pick up a prep kit at least three days before your exam date.

IVP (Intravenous Pyelogram)

Your test requires that you be injected with contrast (an iodine contrast material that enhances the urinary tract). Let the technologist know if you might be pregnant.

It is important that you drink at least one cup of liquid every two hours that you’re awake – the more you drink, the better the exam will be.
