Overview
Other imaging studies for meningioma include MR spectroscopy, MR perfusion, and angiography (DSA).[1] MR spectroscopy study for meningioma demonstrates elevated levels of alanine, glutamine, and choline, as well as a significantly reduced levels of N-acetylaspartate and creatine.[1] MR perfusion study for meningioma demonstrates an elevated value of relative cerebral blood volume (rCBV).[2] Angiography of meningioma demonstrates high vascularization of the tumor due to dual blood supply by both pial (intracranial) and meningeal (extracranial) vessels.[1]
Other Imaging Findings
MR Spectroscopy
- MR spectroscopy imaging may distinguish meningioma from other differential diagnosis. Features include:[1]
MR Perfusion
- MR perfusion imaging may distinguish meningioma from other differential diagnosis. Features include:[2]
- Elevated relative cerebral blood volume (rCBV) value
- Time-intensity curve illustrates a sharp signal drop from baseline with no return to baseline measures.
Angiography
- Angiography of meningioma demonstrates:[1]
