Level 2a consists of 708 MR studies (208 subjects) in the UCSF image database which, following quality review in 2014, were judged to have sufficiently good image quality and protocol compliance for volumetric DCE SER analysis. Rejection criteria included: incomplete volumetric DCE acquisitions, lack of a 2nd post-contrast acquisition, variability in fat suppression across the image, observed patient motion during the DCE acquisition

This data set is not provided as a shared list, as it is not recommended for use in any analysis. It is described here because it is the data set from which the Level 3 (primary aim analysis) set was derived.
Level 2b consists of 707 MR studies (207 subjects) in the UCSF image database
Differences which were submitted to ACRIN at the close of the trial in 2008. Inclusion and exclusion was determined by quality and protocol reviews available at that time. In addition to the exclusion criteria listed for Level 2a, studies done with imaging in the axial plane, in violation of the sagittal orientation specified in the trial imaging protocol, were excluded due to processing limitations of the analysis software. Similarly, bi-lateral sagittal acquisitions (alternating left and right volumetric acquisitions) were excluded.
Specific inclusion/exclusion differences between Levels 2a and 2b:
