Representative case of a LGG with positive IDH1-R132H mutational status. (A) Preoperative axial T2-weighted MR images and (B) contrast-enhanced T1-weighted sequences demonstrate a left frontal hyperintense lesion with non-significant (patchy/faint) CE. (C) 7 Tesla SWI detects only very few hypointense structures and (D) the corresponding colour-coded SWI-LIV map shows low values in the tumour ROI (mean SWI-LIV: 32.2). (E) Histopathological examination reveals a LGG (diffuse astrocytoma WHO grade II) with (F) positive IDH1-R132H mutational status. Original magnification of the H&E stain (E) and IDH1-R132H stain (F) is × 200
