Intraoperative Contrast Enhanced Ultrasound Evaluates the Grade of Glioma

Figure 1

(a) Ultrasound image shows that the low grade glioma (II level) is partially hyperechoic, the boundary is not clear, internal echo is nonuniform, and edema is not obvious (arrow showed tumor). (b) CEUS shows that the echo of the glioma is enhanced significantly, the boundary is clear, and normal brain tissue is enhanced lower than the glioma (arrows show tumor; triangle shows normal brain tissue). (c) MRI T2W image shows that the glioma is hyperintense, irregular, and the boundary is not clear. (d) The pathological image of the same patient shows that the number of capillary vessels is less (HE ×100).
