^*“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.
