WOMEN IN BUSINESS: 3D imaging provides better analysis
BREAST cancer is the most common cancer in women in Australia and the second most common cause of cancer-related death in women, according to Cancer Australia.
It is also estimated by Breast Cancer Australia that up to 15,600 Australian women will be diagnosed with breast cancer in 2015.
Central Queensland Radiology offers 2D and 3D mammograms for the early detection of breast cancer.
Digital mammography creates a 2D picture of the breast tissue and is the most common form of mammography performed on patients.
Breast tomosynthesis, a 3D mammogram, takes a more complete picture of the patient's breast tissue, resulting in a 41% increase in invasive breast cancer detection and a 27% increase in overall breast cancer detection when compared to 2D mammography (Data on file with Hologic, Inc).
A 3D mammogram allows the breast tissue to be examined in thin layers, typically 1mm thick.
During a Genius 3D mammogram exam, the X-ray arm sweeps in a slight arc over the breast, taking a series of images at various angles in just seconds.
The advanced technology converts the digital breast images into a stack of very thin layers or "slices" to build a 3D image.
This results in masses, distortions and asymmetric densities being better visualised, and may reduce the number of biopsies performed on patients.
A 3D mammogram can also be performed in conjunction with a 2D exam for screening purposes or by itself as a diagnostic mammogram.
A diagnostic mammogram provides the benefit of immediate review by a radiologist and can include additional imaging at the same time.
Although research shows all patients can benefit from a 3D exam the following high-risk patient types may be more suited to a diagnostic referral for Genius 3D mammography:
Women with any breast changes, signs or symptoms.
Those with a strong family history of breast or ovarian cancer.
Women with a previous diagnosis of breast disease or those requiring further assessment following a 2D exam.
Patients with dense breasts, e.g. women in their 40s not actively targeted by Breast Screen.

Radiologists who report more than 5000 mammograms per year detect more breast cancers. (Radiology: Vol 269, No 1. Oct 2013.)
Seven of Central Queensland Radiology's radiologists are current Qld Breast Screen readers who report more than 5000 mammograms per year.
All 3D mammograms are dual reported by two experienced imaging radiologists at Central Queensland Radiology.
