Ultrasounds and MRI

A mammogram  is the most common type of breast screening, but other options such as ultrasound  or an MRI  (magnetic resonance imaging) are sometimes offered.

Ultrasound
In many cases, ultrasound is an important complementary tool to mammography particularly where the breast tissue is dense as it is in many younger women. It also enables a doctor to accurately identify an area of the breast when a biopsy is indicated. Also, ultrasound enables the doctor to confirm that the right area has been sampled. Ultrasound uses sound waves instead of radiation so it can be used as many times as needed.


Magnetic Resonance Imaging (MRI)
An MRI scan involves no radiation exposure; it combines the use of a very strong magnet, radio waves and a computer system to provide detailed images of internal structures and soft tissue structures. A Breast MRI scan is, on occasion, used in breast disease to determine the size and number of breast lesions, to examine the other breast and/or surveillance in women with a strong family history of breast cancer and/or women diagnosed with a previous breast cancer.
