^aValues, given in milliseconds, were averaged in different regions of interest (lens nucleus, vitreous body, orbital fat, and extraocular muscle) from the different scans at low resolution, using different reconstruction methods, for each of the 6 healthy volunteers. The resulting values were used to determine mean ± SD values over all volunteers. The CS reconstruction produced different relaxation times in small anatomical regions such as the lens nucleus and the extraocular muscles. The TRs for the MC‐based reconstructions are close to the values for the fully sampled scans. Remaining differences can be explained by motion artifacts that differ from scan to scan. Reference values at 7T (variable flip angle gradient echo/inversion recovery) from previous literature were reported in the last 2 columns, showing large differences in T₁ values between different techniques.
