Overview
Brain MRI is helpful in the diagnosis of atypical teratoid rhabdoid tumor. On MRI, atypical teratoid rhabdoid tumor is characterized by iso- to slight hyperintensity on T1-weighted imaging and hyperintensity on T2-weighted imaging. There is heterogeneous enhancement on contrast administration.
MRI
- Brain MRI may be helpful in the diagnosis of atypical teratoid rhabdoid tumor.
- Findings on MRI suggestive of atypical teratoid rhabdoid tumor are tabulated below:[1]
| MRI component | Findings |
|---|---|
|
T1 |
Iso- to slightly hyperintense to grey matter (hemorrhagic areas can be more hyperintense) |
|
T2 |
Generally hyperintense (hemorrhagic areas can be hypointense) |
|
