Compressed sensing technology can greatly
improve scanning speed at the small expense of a small SNR with unchanged CNR, morphological
measurements and subjective images evaluation score on lumbosacral plexus MR
imaging.
Figure 3. Comparison of the conventional FFE with the FFE-CS. LSP magnetic resonance
neurography images of a 26-year-old woman without lower back pain. The coronal conventional 3D FFE (a) serves as a reference
for the FFE-CS with factor CS2(b) and CS3(c). No difference can be observed among
the three types of FFE, all sequences showing compromised image quality. A
general noise enhancement could be observed in the FFE sequences with
compressed sense. The subjective image quality score for LSP given by the two radiologists was both 3 in the conventional and
compressed sensing sequences.
