  • ACA=anterior cerebral artery; MCA=middle cerebral artery; DSA=digital subtraction angiogram; TCD=transcranial Doppler ultrasonography; CT=computed tomography; MRS=proton magnetic resonance spectroscopy; NAA=N-acetyl aspartate; NS refers to a non-significant asymmetry in relative cerebral blood volume (CBV).
