5/16/2018 DWI: brain claim DWI: liver claim “Whole Body” metrics Brain metrics DWI: prostate claim Joint/MSK metrics Liver metrics Meta-analysis Performed Topics of Discussion • Change in composition of BCs and TFs; role of MR CC • Plans for progression of BC activity beyond profiles • Challenges in anatomic specific vs. generic measurands • New biomarkers in MR? • Biomarkers vs. Phenotypes? • Multi-measurand imaging protocols (e.g liver, prostate, brain) • Role of radiomics 5

5/16/2018 CV T1  CV K trans “Whole Body” metrics Brain metrics fMRI(motor/language)  Resting state fMRI Joint/MSK metrics CV T2*  CV PDFF Liver metrics Meta-analysis Performed Topics of Discussion • Change in composition of BCs and TFs; role of MR CC • Plans for progression of BC activity beyond profiles • Challenges in anatomic specific vs. generic measurands • New biomarkers in MR? • Biomarkers vs. Phenotypes? • Multi-measurand imaging protocols (e.g liver, prostate, brain) • Role of radiomics • Adapting profiles for technological advancements in MR 6

5/16/2018 Profiles v2.0 in MR • DCE: re-evaluate claims for modern imaging • 3T and B1 heterogeneity • Groundwork project  challenge of B1 compensation • Effect of FOV: brain vs body imaging • Vendor-specific differences in B1 mapping protocols •  strong effect on VFA correlations Profiles v2.0 in MR • Next generation of MR imaging • Multi-band excitation/parallel imaging/etc. • Need to recreate claim generation process (“from scratch”?) • Metrology concern: “bias creep” in using last methodology as new ground truth • Liver examples: MRE and PDFF become the “gold standard” • FDA example: leveraging prior knowledge? 7
