![Magnetic resonance neurography of the cervical spine greatly benefits from the signal-to-noise ratio available at 7T. The 3D DESS sequence with water excitation provides excellent visualization of cervical nerve anatomy and intervertebral discs while effectively suppressing surrounding bone and fat tissue. This enables high-contrast images that clearly depict microstructural detail such as intradural rootlets/roots, dorsal root ganglia (DRGs), and the proximal spinal nerves.
A key challenge, however, is the relatively long acquisition time required to achieve the necessary submillimeter isotropic resolution. Extended scan durations make the examination more vulnerable to motion artifacts caused by swallowing, breathing, or cerebrospinal fluid pulsation.
Substantial reductions in scan time can be achieved through coherent (e.g., GRAPPA, CAIPIRINHA) and incoherent (compressed sensing [CS]) undersampling combined with deep learning (DL) reconstruction. Combining CAIPIRINHA and CS with DL reconstruction may enable even greater acceleration while preserving or improving image quality compared to state-of-the-art CAIPIRINHA or CS.
The authors explored a novel joint CS + CAIPIRINHA (CS-CAIPI) data sampling scheme with DL reconstruction for highly accelerated 3D DESS MR neurography at 7T.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:woualjewgsk7yxzre7hi3ij5/bafkreiag77vcvc3y76tfywnvgy6lgjuujgv7vokpwpuhq7p5gyfyw4xmo4)
