Deep learning chemical shift correction improves bone depiction on zero echo time MRI of lumbar spine

Deep learning chemical shift correction (DLCSC) reconstruction of zero echo time (ZTE) MRI significantly improved sharpness, SNR, and bone depiction quality in lumbar spine imaging compared to standard DL and non-DL reconstruction in a retrospective study of 38 patients.

• Retrospective, single-center study of 38 patients undergoing 3T ZTE MRI of the lumbar spine.
• DLCSC improved quantitative sharpness vs. non-DL (p=0.010) and standard DL (p<0.001), with higher SNR and CNR (p<0.001).
• Limitation: small sample, single-center, retrospective, no external validation.
