Normative Reference Values and Age-Related Variation in Advanced Diffusion MRI of the Pediatric Spinal Cord: DTI, DKI, and NODDI Metrics across Cervical and Thoracic Levels Using Hybrid Diffusion Imaging.
BACKGROUND AND PURPOSE Normative diffusion values are essential for detecting microstructural abnormalities in the spinal cord. While diffusion kurtosis imaging (DKI) and neurite orientation dispersion and density imaging (NODDI) provide additional sensitivity beyond DTI, existing normative datasets are limited to adul...
