Hey et al. (Magn Reson Med. 2011 Nov 2. doi: 10.1002/mrm.22987) a reference to the used B1 mapping technique was omitted on page 6, line 10. It should read correctly: B1 inhomogeneity was corrected by acquiring a B1 map before image acquisition using a three-dimensional radio frequency-spoiled gradient echo sequence (27) (echo time = 1.48 ms, TR1/TR2 = 23/115 ms, flip angle = 70°, field of view = 250 × 250 × 42, matrix = 64 × 63, voxel size = 4 × 4 × 6 mm3 bandwidth in readout direction = 1085 Hz, seven slices) with increased gradient spoiler amplitudes (28).
