**[[Choline]] (Cho):** Marker of cell membrane turnover and proliferation, often elevated in tumors.

**[[N-Acetylaspartate]] (NAA):** Marker of neuronal integrity, typically reduced in areas of damage or tumor infiltration.

**Interpretation:**

**Higher [[Cho]]/[[NAA]]:** Indicates increased tumor activity, malignancy, or infiltrative processes.

Used to differentiate tumors from non-tumor conditions and to assess [[glioblastoma recurrence]].
