This type of analysis can be used on different MR sequences or CT slices. Yet, portrayed texture from necrosis, which may be important to detect during LGG transformation, may be…

Fig. 12.1 (a) Example of a left parietal diffuse low-grade glioma. Brain tissue specimens were sampled inside the tumor (Tu) and from the neocortex infiltrated by sparse glioma cells (Cx)….

Fig. 22.1 Proposal of a hodotopical model of functional connectivity in the human brain, with incorporation of anatomical constraints. This networking model was elaborated on the basis of structural-functional correlations…

Fig. 19.1 Motor fMRI. A low grade glioma was located in the right superior frontal gyrus, anteriorly to the precentral sulcus. Presurgical fMRI shows primary sensorimotor activation of the left…

Fig. 11.1 MRI of a patient with an oligodendroglioma WHO grade II in the right frontal pole. A right frontal lobectomy was performed with en-bloc removal of the tumor. Postoperative…

Fig. 4.1 (a) This infiltrating astrocytoma has hyperchromatic elongated astrocytic nuclei as often seen in the prototypic infiltrating astrocytomas but a significant proportion of tumor cells exhibit abundant globose eosinophilic…
