Fig 4. A–H, Anaplastic astrocytoma (grade III/IV). Top row, left to right.
A, Axial FLAIR image (TR/TE/TI, 9000/110/2500 ms) demonstrates a dominant lesion in the right thalamus with extension to the left thalamus and parietooccipital region.
B, Axial T1-weighted postcontrast image (TR/TE, 600/14 ms; 1 excitation) demonstrates heterogeneous contrast enhancement in keeping with an anaplastic astrocytoma.
C, Gradient-echo axial DSC MR image (TR/TE, 1000/54 ms).
D, SD25 color map shows foci of increased permeability throughout the lesion.
E–G, Bottom row (left to right). rCBV, CBV, and CBF maps demonstrate elevated rCBV, CBV, and CBF within the glioma.
H, MTT map demonstrates some prolongation in MTT within the tumor.
