Data
57,277 bulk items are available, covering 52,868 participants.
Defined-instances run from 2 to 3, labelled using Instancing

The values held within this field are coded links to files held within a bulk repository, not the actual data itself.

Notes
The DICOM images were acquired using the following parameters:
Resolution: 2.4x2.4x2.4 mm
Field-of-view: 88x88x64 matrix
Duration: 4 minutes (332 timepoints)
TR: 0.735 s
TE: 39ms
GE-EPI with x8 multislice acceleration, no iPAT, flip angle 52 degrees, fat saturation
As implemented in the CMRR multiband acquisition, a separate "single-band reference scan" is also acquired. This has the same geometry (including EPI distortion) as the timeseries data, but has higher between-tissue contrast to noise, and is used as the reference scan in head motion correction and alignment to other modalities.
