Overview
Head and neck MRI may be helpful in the diagnosis of nasopharyngeal carcinoma. Findings on MRI suggestive of nasopharyngeal carcinoma include dural thickening and bone marrow infiltration.

- Fat saturation in post contrast sequencse
- Notable heterogeneous enhancement is typical
- Perineural extension should be sought

- Isointense to hyperintense to muscle signal
- Fat saturation
- Fluid in the middle ear can be helpful

- The protocol for routine MRI of a nasopharyngeal mass includes:[2][3][4][5][6]
- Unenhanced T1- weighted axial and sagittal plane images for:
- Detection of skull base invasion
- T2-weighted fast spin-echo sequence in axial plane images for:
- Evaluation of early parapharyngeal tumor spread
- Invasion to the paranasal sinus
- Effusions of the middle ear
- Detection of cervical lymph nodes.
- Contrast-enhanced T1-weighted axial and coronal planes images (with and without fat suppression) for:
- Evaluation of tumor extension to the perineural and intracranial space.
- Unenhanced T1- weighted axial and sagittal plane images for:
- Additional MRI component:[7][8][9]
- Diffusion-weighted imaging for:
- differentiating NPC from lymphoma
- characterizing of cervical lymphadenopathy
- MRI spectroscopy for:
- Differentiating of the NPC and metastatic nodes from normal neck muscle.
