Data
76,476 bulk items are available, covering 71,627 participants.
Defined-instances run from 2 to 3, labelled using Instancing
2.
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: 0.8x0.8x3 mm
Field-of-view: 256x288x48 matrix
Duration: 2.5 minutes
Two echos, TE=9.42,20 ms
2D, axial, in-plane acceleration iPAT=2, partial Fourier = 7/8, prescan-normalise
To date (Oct 2015) the magnitude and phase images have been saved for each RF coil and echo time separately. In future the expectation is to combine these on the scanner
