FIGURE 4

Panel (a) depicts a right frontal glioblastoma in a 40‐year‐old male and panel (B) depicts a right temporal anaplastic astrocytoma in a 32‐year‐old female, with high signal on fluid‐attenuated inversion recovery (FLAIR), low signal on T1‐weighted imaging, and partial contrast enhancement according to contrast‐enhanced T1‐weighted imaging. Intratumoral susceptibility signal (ITSS) abnormalities can be found according to susceptibility‐weighted imaging (SWI) in both patient cases (a: multiple dot‐like and fine linear ITSS abnormalities corresponding to ITSS grade 3, red arrowheads point at a prominent linear ITSS within the lesion; b: only few dot‐like ITSS abnormalities corresponding to ITSS grade 1, red circles enclose two exemplary dot‐like signal drops within the lesion).
