Overview
Other imaging studies for meningioma include magnetic resonance (MR) spectroscopy, magnetic resonance (MR) perfusion, and angiography.[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. 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
Magnetic resonance spectroscopy
- Magnetic resonance (MR) spectroscopy imaging may help distinguish meningioma from other CNS masses. Features include:[1]
Magnetic resonance perfusion
- Magnetic resonance (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]
