Bankstown Lidcombe Medical Imaging has installed a state of the art, new 3D Tomosynthesis unit to capture premium quality images and improve diagnostic outcomes.

Three-dimensional (3D) mammography, also known as breast tomosynthesis, is a type of digital mammography in which x-ray machines are used to take pictures of thin slices of the breast from different angles.

Mammograms are performed for two major reasons. First, in women with breast symptoms, to detect a possible cause for their symptoms (a diagnostic mammogram), and secondly, to detect early signs of breast cancer in women who do not have breast symptoms (a screening mammogram).

  • Preparation

    1. The first step in the process is for us to find out what is on the request form that your doctor gave you for this test. This may involve you coming into our rooms and showing our front desk staff the form. Or you can fax or email the form to us (see contact us). Or maybe you can read out what is on the form over the phone to one of our front desk staff. We need to know what kind of test is requested, what part of the body the test is requested for and what the problem is.
    2. Please wear clothing where the top can be removed (eg shirt with trousers or skirt).
    3. Please shower on the morning of the appointment. Do not use any deodorants, antiperspirants, powders, lotions, creams or perfumes on the day of the appointment. These products can contain metallic substances that can show up on the mammogram and make the examination difficult.

  • What is Mammography?

    A mammogram uses xrays. Mammography uses several techniques to optimise the images produced, and to minimise the amount of radiation used. Xrays are shone through the breast and form shadows on the screen. These shadows are not as distinct as other xrays since there are no bones in a breast to give distinct shadows on an xray. So several techniques are used to optimise the mammography images while minimising radiation dose. One thing that is done is to compress the breast. This reduces the distance the xrays have to go to go through the breast. So less radiation is absorbed and more xrays go to make up the images. Also the breast is held in a specific position and as still as possible to improve the images. Specialised screens and xray producing machines are used that are specifically designed for mammography. You may feel moderate pressure during the compression. The compression will be applied for as little time as possible. But if the compression becomes too uncomfortable, please let the technician know and it will be released or reduced.

  • Tomosynthesis

    Another new technology is TOMOSYNTHESIS – here specialised machinery is used to obtain images of the breast at multiple angles, which a high powered computer manipulates to form a 3D image (or multiple images) of the breast. This reduces the amount of times the breast needs to be irradiated and also gives significantly more detail about specific parts of the breast. At Bankstown Lidcombe Medical Imaging, we have the latest 3D mammography equipment. This allows more detail, with higher accuracy in diagnosis, and so gives the patient and the referring doctor more peace of mind. 3D mammography allows the radiologist to detect abnormalities that are not detected by traditional mammography, often due to variations in the density of the breasts or due to the small size of the abnormalities. This increased detection helps radiologists detect breast cancers earlier than previously possible, allowing for better treatment options and improved outcomes.
