In 2017 the EUSOBI established an international working group on diffusion weighted imaging of the breast. Its first mission and consensus statement was recently submitted to European Radiology.

We call upon you to query your interest for participation in this working group!

For your convenience the abstract of the paper is presented below:

The European Society of Breast Radiology (EUSOBI) established an International Breast DWI working group. The working group consists of clinical breast MRI experts, MRI physicists and representatives from large vendors of MRI equipment, invited based upon proven expertise in breast MRI and/or in particular breast DWI, representing 25 sites from 16 countries. The aims of the working group are: a) to promote the use of breast DWI into clinical practice by issuing consensus statements and initiate collaborative research where appropriate; b) to define necessary standards and provide practical guidance for clinical application of breast DWI; c) to develop a standardized and translatable multi-site multi-vendor quality assurance protocol, especially for multisite research studies; d) to find consensus on optimal methods for image processing/analysis, visualization, and interpretation; and e) to work collaboratively with system vendors to improve breast DWI sequences. First consensus recommendations, presented in this paper, include acquisition parameters for standard breast DWI sequences including specifications of b-values, fat saturation, spatial resolutionand repetition and echo times. To describe lesions in an objective way, levels of diffusion restriction/hindrance in the breast have been defined based on the published literature on breast DWI. The use of a small ROI placed on the darkest part of the ADC map, avoiding necrotic, noisy or non-enhancing lesion voxels is currently recommended. The working group emphasizes the need for standardization and quality assurance before ADC thresholds are applied. The working group encourages further research in advanced diffusion techniques and tailored DWI strategies for specific indications.

While we made great progress with the draft of our paper we realize there are many subjects that still require specific attention.

We recognize 3 overarching fields:

  1. Clinical implementation
    (BIRADS integration, reading protocols, therapy evaluation, radiomics etc.)
  2. Standardization and quality control
    (Sequence standardization, phantom development, SNR measurement etc.)
  3. Advanced diffusion based imaging techniques
    (DTI, IVIM, Kurtosis imaging etc.)

We realize that in each of these fields several important topics must be addressed. This can only be done with active contribution from experts in the field. We realize that not everyone who is interested might have been involved from the start. Consequently, we call again upon you to query your interest for participation in this working group.

We intend to spread our efforts over the different fields, tackling as many subjects simultaneously as allowed by the participation in the group.

We therefore ask you:

  1. to indicate whether you are interested in a participation in the working group
  2. to indicate which field has your main interest
  3. to indicate on which topic you would like to work

Please send an email to before January 6, 2019

We plan on preparing a face-to-face meeting at ECR to discuss the following steps.
