3D Digital Mammography (Tomosynthesis) Hologic Selenia Dimensions

Video of patient experience in Digital Mammography

Mammograms are specialised low dose x-rays of the breast. SVCMI&NM has a leading technology mammography machine (Hologic Selenia Dimensions) which has the capability of performing both standard 2D mammography and 3D tomosynthesis. Tomosynthesis is a recent development in breast imaging technology that involves acquiring images of a stationary compressed breast at multiple angles during a short scan.  The benefits of tomosynthesis include improved cancer detection and lesion characterisation, more precise localisation of diagnosed lesions and reducing or eliminating tissue overlap that can obscure or simulate true lesions, particularly in dense breasts.

The very low radiation dose for conventional 2D mammography is increased with the addition of 3D tomosynthesis. However this is offset by the benefit of decreasing the need for additional images to clarify 2D imaging findings. With latest C-view technology, 2D mammogram views of the breasts are replaced by synthesised images from tomographic scans, thereby reducing the total examination dose to just above the equivalent dose for conventional mammography alone.

Mammography requires compression of the breast to ensure that high quality images are obtained and the dose kept as low as possible. An ergonomic flex paddle that shapes to the breast is used to ensure even compression throughout the whole breast that helps to minimise any discomfort felt during the examination. Once the images are obtained they are sent to our radiologist's high resolution monitors for review and reporting, following which they are stored on our PACS (Picture Archiving Communications System). These images can be recalled at the time of your next appointment so that a direct comparison can be made. We print a set of films for your personal records.

Breast Ultrasound - Philips IU22 with matrix probe

Breast ultrasound uses sound waves emitted from an ultrasound transducer, a hand held device, that is placed on your skin over the breast being examined and the reflected sound waves are analysed by a computer and turned into images. There is no use of x-rays or ionising radiation. High resolution images are produced that can show the characteristics of breast tissue and the location and appearance of any lesions.

Ultrasound is often used to complement mammography.

Breast MRI Siemens MAGNETOM 3T Verio Open Bore MRI

MRI is also a complementary modality to mammography and ultrasound used for further investigation of breast cancer, especially in young women, those with dense glandular breast tissue and surveillance of high risk patients.

Breast MRI does not attract a Medicare rebate for all women at this stage. A rebate is available to women referred by a specialist where the woman is less than 50 years of age, with no symptoms and at high risk of developing breast cancer who also meet a rigid set of criteria set by Medicare.
