Quantification of intervertebral disc degeneration using dual-energy computed tomography collagen maps: a comparative study with MRI Pfirrmann grading
To determine the correlation between quantitative HU values derived from DECT collagen maps and the MRI-based Pfirrmann grade. We retrospectively reviewed IVDs in patients who underwent both spinal DECT and MRI within one year. CT scans were acquired using single-source DECT at 80 and 135-kVp with automatic exposure co...
