Ultra-fast detection of breast density using MRT

A high breast density is an independent risk factor for breast cancer. MRT is the safest method for breast cancer diagnosis and is now used for early diagnosis. Medical University Vienna researchers have now successfully developed a method for the exact measurement of breast density using magnetic resonance tomography (MRT) examinations with the Dixon sequence.

With this, in addition to a better breast cancer diagnosis, a better assessment of the risk is also possible.

For the first time worldwide an objective measurement of breast density, with fully automatic software and higher precision and reproducibility, has been detected with this method, and a prototype currently exists. "It works practically at the touch of a button and only takes a few minutes. There is also no need to provide contrast material", says Georg Wengert from the University Clinic for Radiology and Nuclear Medicine at Medical University Vienna. The study was undertaken by the Molecular and Gender Imaging Working Group under the management of Thomas Helbich (University Clinic for Radiology and Nuclear Medicine) and the Computational Imaging Research (CIR) Laboratory developed the software under the management of Georg Langs (University Clinic for Radiology and Nuclear Medicine).

Breast density is divided into four categories according to the guidelines of the ACR (American College of Radiology): Ranging from A to D, the risk of getting breast cancer is considered to be four to six times higher for a higher breast density (C/heterogeneous and D/extremely dense). The density cannot be precisely measured using mammography and an ultrasound scan, and additionally a high breast density makes diagnosis more difficult.

That is why Medical University Vienna experts recommend increasing the use of MRT for risk assessment, diagnosis and early diagnosis: "We are committed to better explaining to women that the use of mammography and ultrasound alone cannot detect all carcinomas. MRT really is the recommended method", says Wengert. The examination has a far better validity, and therefore helps to quickly introduce the right therapeutic steps.
