* “Relative Signal Intensity Ratio” denotes relative signal intensity ratio of intra- and extracranial components of JFM to CNS tissue at the same level.
** “hyperintense” denotes that signal intensity of the intracranial component of JFM is higher than that of the extracranial component.
*** “isointense” denotes that the signal intensity of the intracranial component of JFM is equal to that of the extracranial component.
**** N/A denotes not applicable.
