Overview
Other imaging studies for gliomatosis cerebri include MR spectroscopy (decreased NAA/creatine ratio and 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 on F-18 FDG PET, hypermetabolism on C-11 methionine PET, and marked increase in cerebral blood flow on 15(O)-water PET), and bone scan (metastasis to bones).[1][2][3][4]
Other Imaging Findings
Other imaging studies for gliomatosis cerebri include:[1][2][3]
1. MR Spectroscopy
MR spectroscopy may be helpful in the diagnosis of gliomatosis cerebri. Findings on MR spectroscopy suggestive of gliomatosis cerebri include:[1][3]
- Decreased NAA/creatine ratio
- Elevated choline/creatine ratio
- Elevated choline/NAA ratio
- Elevated myoinositol
2. MR Perfusion
MR perfusion may be helpful in the diagnosis of gliomatosis cerebri. Findings on MR perfusion suggestive of gliomatosis cerebri include:[1]
- Low/normal relative cerebral blood flow (no vascular hyperplasia)
3. PET
PET scan may be helpful in the diagnosis of gliomatosis cerebri. Findings on PET scan suggestive of gliomatosis cerebri include:[1][2]
- F-18 FDG PET images show markedly decreased accumulation of [18F]-fluorodeoxyglucose (glucose hypometabolism).
- C-11 methionine PET images show hypermetabolism.
- 15(O)-water PET images show a marked increase in cerebral blood flow in gliomatosis cerebri lesions.
4. Bone Scan
- Most malignant gliomas get metastasized to the bones via the hematogenous spread.[4]
- Bone scan may be performed to detect metastases of gliomatosis cerebri to bones.
