Overview
MRI
MRI may be helpful in the diagnosis of astrocytoma. Findings on MRI suggestive of astrocytoma include:[1][2]
- Low grade astrocytoma (pilocytic and diffuse astrocytoma)
- T1: Decreased resonance in comparison to surrounding brain tissue
- T2: Increased resonance in comparison to surrounding brain tissue
- High grade astrocytoma
- Anaplastic astrocytomas
- Hypointense T1
- Hyperintense T2
- There might be some contrast enhancement and edema
- Glioblastoma multiform
- Irregular ring-nodular enhancing lesions
- Central necrosis
- Surrounding vasogenic edema
- Anaplastic astrocytomas
Pilocytic astrocytoma
Diffuse astrocytoma
Anaplastic astrocytoma
Glioblastoma multiform
