What is a contrast enhanced mammogram?
A Contrast Enhanced Spectral Mammogram (CESM or CEM) provides additional information beyond a conventional mammogram and may result in earlier detection of some cancers. CEM has been shown to detect cancers that may not be shown on a mammogram.
Understanding your contrast enhanced mammogram
Your doctor may recommend Contrast Enhanced Mammography (CEM) if you:
- Are at an increased risk for developing breast cancer, such as having a personal history of breast cancer, a high family risk, or genetic predisposition.
- Have high-density breasts, which can make it more difficult to detect abnormalities with standard mammograms.
Before your contrast enhanced mammogram:
- Please let us know if you:
- Have had kidney disease or poor kidney function.
- Have ever had an allergic reaction to iodinated contrast in the past.
- If you are a diabetic on metformin or a woman over 65 years of age, a blood test to check your kidney function may be necessary.
On the day of your contrast enhanced mammogram:
- When you arrive, please check in with reception. We’ll make sure your details are correct and ask you to complete any appropriate consent forms.
- Please do not use talcum powder or deodorants on the day of your examination as they can show up on the mammogram images.
- If your breasts are tender or sore before your period, you should try to arrange to have your mammogram just after your period finishes
- You will be asked to undress from the waist up and put on a gown.
During your contrast enhanced mammogram:
- Your mammogram will be performed by a Medical Imaging Technologist (MIT) with specialised training and experience (mammographer).
- Prior to the exam, a small IV line will be placed and iodinated contrast dye will be injected into your arm. After the injection, you will wait two minutes to allow the contrast agent to flow into your breast.
- The technologist will then perform the mammogram, which is very similar to having a conventional mammogram.
- There is no additional compression required other than what is generally required for a conventional mammogram
- Please allow approximately 30 minutes for your visit.
After your mammogram:
- You can resume normal activities after your mammogram.
- The images will be interpreted by a radiologist, and your report will be sent to your referring clinician.
