The authors apologize for any inconvenience caused and state that the scientific conclusions are unaffected. The original article has been updated.
Figure 3.
Average and peak recovery coefficients from the Micro Hollow Sphere phantom. For an acquisition time of two minutes per bed position, the apparent RCavg (a) of the 8 mm sphere measured with T/B ratio 10:1 exceeds that of the bigger spheres for low β, as the center of this sphere happened to coincide with the center of a voxel. Taking RCpeak as a measure for the recovery coefficient (b), the recovery coefficients are lower, but more robust.
