Table 1
Summarizing CEUS features of different grades of human cerebral gliomas.
| Brain Lesion | Number of pts. | Echogenicity | Appearance | Cystic areas and/or necrosis | Arterial phase | CEUS peak | Venous phase | CE |
| Low-grade glioma | 22 | Iso/hyperechoic | Diffuse; homogeneous | Small/microcysts | 15′′ | 20′′ | 30′′ | Mild | Anaplastic glioma | 11 | Iso/hyperechoic | Diffuse; homogeneous | Small/microcysts | 10′′ | 15′′ | 20–25′′ | Mild/high | Glioblastoma | 36 | Hyperechoic | Diffuse/circumscribed; heterogeneous | Large necrotic areas | 2-3′′ | 5′′ | 10′′ | High |
