Fast Spin Echo (FSE) is widely used in MR imaging due to
its speed and robustness to image artifacts. However,
blurring due to T2 decay inhibits its use for 3D
musculoskeletal imaging. By compensating for signal
decay and reconstructing a time series of images, the
blurring can be reduced. In this work we resample and
reorder phase encodes over a longer echo train length to
improve scan efficiency. We add a locally low rank
constraint to improve the conditioning of the
reconstruction, producing multicontrast 3D FSE images at
clinically feasible scan times.
