Declarations
:
: The scientific guarantor of this publication is Pascal Baltzer.
: The authors of this manuscript declare no relationships with any companies whose products or services may be related to the subject matter of the article. Paola Clauser and Katja Pinker are members of the <i>European Radiology</i> Scientific Editorial Board. They have not taken part in the review or selection process of this article.
: One of the authors (Pascal Baltzer) has significant statistical expertise.
: For this retrospective study, data from multiple previous prospective studies were analyzed. In the course of these previous studies, written informed consent was obtained from all included subjects (patients).
: Institutional review board approval was obtained.
: Since this is a retrospective analysis of multiple study populations, some of the original data analyzed in this study have, at least in part, already been analyzed and published with different research questions.The according most recent publications are referenced below:-Bickel, H. et al Quantitative apparent diffusion coefficient as a noninvasive imaging biomarker for the differentiation of invasive breast cancer and ductal carcinoma in situ. <i>Investigative Radiology</i> 50, 95–100, ExternalRef removed (2015).-Clauser, P. et al Is there a systematic bias of apparent diffusion coefficient (ADC) measurements of the breast if measured on different workstations?
