OR
There are no MRI findings associated with [disease name]. However, a MRI may be helpful in the diagnosis of complications of [disease name], which include [complication 1], [complication 2], and [complication 3].
MRI
- MRI is the imaging modality of choice for pleomorphic adenoma.[1]
- On T1-weighted images:
- Pleomorphic adenoma's show homogeneous intensity. [2]
- On T2-weighted images:
**Marked hyperintensity reflects abundant myxochondroid stroma.[3]
- Hypointensity reflects the fibrous capsule.[3]
- On Gd-T1weighted images:
- It shows heterogeneous enhancement.[2]
