Overview
Other Imaging Findings
Magnetic Resonance Spectroscopy
- MR spectroscopy may be helpful in the diagnosis of intracerebral metastases.[1]
- Findings on MR spectroscopy include:[1]
- Intratumoural choline peak with no choline elevation in the peritumoral edema
- Any tumor necrosis results in a lipid peak
- N-Acetylaspartate (NAA) depleted
Magnetic Resonance Perfusion
- MR perfusion demonstrates reduced CBV (cerebral blood volume) and CBF (cerebral blood flow) in the region of metastasis. Surrounding edema demonstrates normal CBV.
