MRS in AVM patient (#2) with normal post-interventional state. Radiogenic changes after treatment are seen as hyperintensities in axial FLAIR (a) and sagittal contrast-enhanced MRI (b). c: SV-spectrum from 6 mL-VOI (yellow frame in a, b) in AVM lesion reveals a moderately increased Cho/Cr ratio of 1.38 and smaller signal from lipids.
