How to Prepare for your Imaging Procedure

If you are scheduled for an imaging procedure at St. Mark’s, there are a few things you should do in advance of your appointment to prepare. Following are some general instructions to follow; however, different exams can require different preparation. You should be informed of how to prepare for an exam when you make an appointment. If you need more information, call St. Mark’s Imaging Services at (801) 268-7100 to get instructions on how to prepare for your specific imaging procedure.

Ultrasound

Wear comfortable, loose-fitting clothing for your ultrasound exam. You may be asked to remove all clothing and jewelry in the area to be examined (you may be asked to wear a gown). Other preparation depends upon the type of exam – for some exams, you may be asked not to eat or drink for 12 hours before your appointment while other exams might require you to drink up to six glasses of water two hours before your appointment.

Digital Mammography

The American Cancer Society recommends discussing any new findings or problems with your breasts with your doctor before scheduling a mammogram. The best time to schedule a mammogram is during the week after your period. Do not schedule your mammogram for the week before your period if your breasts are usually tender during this time. Always inform your doctor or x-ray technologist if there is any possibility that you are pregnant. The ACS also recommends not wearing deodorant, talcum powder or lotion under your arms or on your breasts on the day of the exam.

Magnetic Resonance Imaging (MRI)

You should wear loose-fitting clothing, but know that you may be asked to wear a gown during the exam if needed. Guidelines for eating and drinking before an MRI exam vary by procedure. You may have to receive an injection of contrast material in the bloodstream; the radiologist or x-ray technologist will make sure you have no allergies before performing this injection. Let the technologist know if you have any metal implants, medical or electrical devices in the body - some of these could interfere with the exam or pose a risk. If you are claustrophobic and have anxiety, you may want to ask your physician for a prescription for a mild sedative prior to your scheduled exam.

Nuclear Medicine Scan

You may be asked to wear a gown during the procedure. Inform the physician or technologist if there is any possibility you are pregnant and what medications you are taking. Further specific instructions vary based on the type of scan you're getting.

CT Scan

You may be given a gown to wear during the procedure and asked to remove metal objects that you're wearing like jewelry, eyeglasses, dentures, hairpins, etc. You also may be asked not to eat or drink anything for several hours before your exam. Always inform your doctor of any recent illnesses or medical conditions, or if there is a possibility you are pregnant.
