3D mammography aids breast cancer detection

The results come as a study gets underway in Victoria to examine whether the use of tomosynthesis as a diagnostic tool can reduce investigations and cut the rate of benign biopsies. 

The Oslo trial of 12,631 women found a 27% increase in the detection of all cancers and a 15% decrease in false-positives when 3D mammography was used along with conventional 2D mammography. 

Tomosynthesis captures slices of breast tissue that can be stacked and reviewed one after the other. 

Dr Darren Lockie, a radiologist with Maroondah BreastScreen, Eastern Health in Victoria, said the Oslo trial showed tomosynthesis improved both the sensitivity and specificity of imaging. 

Preliminary results from his trial of at least 540 women will be available by mid-year. 

“We would hope the results will inform... BreastScreen Australia about possible future use of the technology,” Dr Lockie said.
