<prompt> Answer this question truthfullyWhat other imaging findings are associated with Meningioma?  <response>: <reason> Diffusion MRI may be helpful in the diagnosis of meningioma. Findings on an diffusion MRI suggestive ofdiagnostic of meningioma include: Reduced water diffusivity which is seen more in aggressive tumors and atypicalmalignant meningiomas A decrease in the apparent diffusion coefficient raises suspicion that a tumor has differentiated to a higher grade on follow up of a benign meningioma.Magnetic resonance spectroscopy may be helpful in the diagnosis of meningioma. Findings on an MR spectroscopy suggestive ofdiagnostic of meningioma include: Elevated alanine Elevated choline Cho Absent or significantly reduced N-acetylaspartate NAA Absent or significantly reduced creatine Cr Elevated lactatePerfusion MRI may be helpful in the diagnosis of meningioma. Findings on an perfusion MRI suggestive ofdiagnostic of meningioma include: Elevated relative cerebral blood volume rCBV value
