Overview
Other imaging studies for gliomatosis cerebri include MR spectroscopy (elevated choline/creatine ratio, choline/NAA ratio, and myoinositol), MR perfusion (low/normal relative cerebral blood flow), PET scan (markedly decreased accumulation of [18F]-fluorodeoxyglucose), and bone scan (metastasis to bones).[1]
Other Imaging Findings
Other imaging studies for gliomatosis cerebri include MR spectroscopy (elevated choline/creatine ratio, choline/NAA ratio, and myoinositol), MR perfusion (low/normal relative cerebral blood flow), PET scan (markedly decreased accumulation of [18F]-fluorodeoxyglucose), and bone scan (metastasis to bones).[1]
1. MR Spectroscopy
Other imaging studies for gliomatosis cerebri include MR spectroscopy. Common findings are described below:[1]
- Elevated choline/creatine ratio
- Elevated choline/NAA ratio
- Marked elevation of myoinositol
2. MR Perfusion
Other imaging studies for gliomatosis cerebri include MR perfusion. Common findings are described below:[1]
- Low/normal relative cerebral blood flow (no vascular hyperplasia)
3. PET
Other imaging studies for high-grade gliomas include PET scan, which demonstrates markedly decreased accumulation of [18F]-fluorodeoxyglucose) (glucose hypometabolism).[1]
4. Bone Scan
Bone scan may be performed to detect metastases of gliomatosis cerebri to bones.
