"Intercaudate distance to inner table width ratio (CC/IT) is used in assessing patients with neurodegenerative diseases that affect the caudate nuclei. It is best known for assessing individuals with suspected Huntington disease but is in no way specific for the diagnosis, also seen in other less common diseases (e.g. Nasu Hakola disease). An alternative measurement is the frontal horn width to intercaudate distance ratio (FH/CC)."
