↵* Used for RNA expression analysis.
Localization of lesions was determined in descriptive manner for MRI, histology, and 18F-FDG PET/CT. For MRI, lesions were categorized as without contrast enhancement (−), with contrast enhancement being present (+), or with strong contrast enhancement (++). The PET signal was classified as mild (+), moderate (++), or strong (+++). If there is no side specified, lesion is central or within whole cross-section.
C = cervical spinal cord; T = thoracic spinal cord; L = lumbar spinal cord.
