- MRI can easily differentiate between benign and malignant parotid lesions by evaluating
- lesion margins,
- SI of cystic content,
- extraglandular infiltrative growth pattern,
- cervical lymph nodes,
- Ill defined images will suggest malignancy
- Hypointense capsule and well defined margins are characteristic of benign lesions
