Mammogram and Breast Ultrasound Information

A mammogram and breast ultrasound are imaging tests used to examine breast tissue and help detect any abnormalities. These tests may be used to investigate symptoms, monitor breast health, or assist with early detection of breast cancer. 

A mammogram is a low-dose X-ray specifically designed for breast examination. It is commonly performed for patients over the age of 35 and can help detect changes in breast tissue, sometimes before symptoms appear. During the procedure, you will stand in front of the X-ray machine while each breast is gently compressed between two plates to obtain clear images. Usually, several images are taken, and the examination typically takes around 30 minutes. 

A breast ultrasound uses high-frequency sound waves to create images of the inside of the breast. Unlike mammography, ultrasound does not involve radiation. During the scan, you will lie on an examination couch while a small handheld device called a transducer is moved over the skin. A clear gel is applied to help the device make contact with the skin and produce clear images. Ultrasound is often used to further assess areas seen on a mammogram or to examine breast tissue in younger patients. 

There is no special preparation required for either test. However, it is important to inform the Imaging Department if you have had any previous breast imaging, including where and when it was performed. If you have copies of previous images on a disc, please bring them with you to your appointment. 

If you are experiencing breast symptoms, it is advisable your GP refer or you self-refer to the Hospital’s Breast One Stop Clinic for a full assessment, as a mammogram alone may not always provide enough information for a definitive diagnosis.
