Comparison SENSE and compressed SENSE. Slices of a retrospectively under-sampled 3D T2 weighted TSE data set reconstructed with different acceleration factors and sampling methods (SENSE/Compressed SENSE) using a 15-element head coil (voxel 1.0×1.0×1.2 mm³, 3T). Formally the 4×4 accelerated case is already under-determined. The advantage of variable density sampling and compressed sensing reconstruction over SENSE is obvious. Please note that there is no claim that the 4×4 variable density CS image is of clinical diagnostic value.
