2016-Y DSC-MRI (Erickson) QIBA Dynamic Susceptibility Contrast (DSC) Digital Reference Object (DRO) Generator The purpose of this website is to provide researchers with images (DROs) that simulate the expected behavior under conditions of a DSC acquisition. There are 3 models currently supported. Please select one of them: MGH Mayo BNI 2016-Z DCE-MRI (Nayak) 6
Profiles Development - Challenges Paucity of published test-retest data Challenges in re to exogenous contrast (gadolinium) Not amenable to coffee-break test-retest evaluation Public/ethical concerns re gadolinium deposition Broader literature search methods required Meta-analyses to aggregate results of small studies Profiles Development - Challenges Global versus anatomic- (context-)specific claims Anatomic variation in MRI techniques/repeatability Adds complexity to profile writing Defining claims Crafting technical section 7
Profiles Development - Challenges Shifting clinical environments affects claims DCE-MRI example v1.0 global, longitudinal claims v2.0 anatomically-segregated, longitudinal claims Future re T1-based perfusion methods? Anatomically-segregated Cross-sectional (diagnostic over therapy response) Declining role of pharmacokinetic modeling? MR CC Other Topics Past/ongoing/future trans-organizational efforts Outreach to other scientific groups EIBALL/EIBIR (ASL) ASNFR (fmri), Japan Rad. Society (MRE) IMI-QUIC-CONCEPT (DWI) Interactions with QIDW Populate existing data sets Phantoms/DROs Retrospective clinical image collection Prospective human testing data 8
Summary for MR CC Recent rapid growth in number of biomarkers Organizational issues within MR CC BC versus TF? Technique-based vs. organ/context relevance Future growth/development Resource allocation among BC s and TF s Source of future GW project funding? Strategic profile timelines Broaden cross-organizational efforts 9
