Simple MRI Measurement Could Avoid 30% of Breast Biopsies
Scientific findings are instantly applicable in clinical practice
March 9, 2021 Breast cancer is the most common fatal cancer in women. Early detection increases a woman s chances of recovery. Magnetic Resonance Imaging (MRI) is an accurate technique for detecting and classifying tumors in breast tissue. However, it sometimes causes false alarms , thus requiring further investigation (biopsy) and in some cases even resulting in so-called overtreatment, that is to say unnecessary surgery. For the first time, a research team from MedUni Vienna has now confirmed a threshold value for a non-invasive imaging biomarker. This can be incorporated into short standard MRI scans and could reduce the biopsy rate following MRI scans by 30%. Since the infrastructure for this measurement already exists in every radiological facility in Austria, the biomarker could be immediately deployed countrywide.

Use of Breast MRI Screening in Women With Dense Breasts
Interview with Professor Christiane Kuhl, M.D., director of radiology, University Hospital Aachen, Germany, on the use of MRI breast screenings
A comparison of standard mammography imaging (left) in a woman with dense breasts and a breast MRI imaging study (right) showing a clearly defined cancer and is extremely hard to detect on the mammograms. Images from Christiane Kuhl, M.D.
Dense breast tissue can hide cancers in mammograms in about half of women. Supplemental imaging is often needed to accurately diagnose these patients, avoid false positives and avoid needless tissue biopsies. Breast ultrasound and breast magnetic resonance imaging (MRI) can be used to see through dense tissue to better identify cancers and avoid the need for many biopsies, however, MRI offers more specificity.
