Imaging is only required if it may change management
Imaging of Primary
- T1 / T2
- Minority require imaging
- CT / MRI to exclude thyroid cartilage or prevertebral tissue invasion if tumour immobile at examination under anaesthesia
- T3/4
- CT / MRI rarely helpful if total laryngectomy planned
- If total laryngectomy planned: consider CT / MRI if concern about extrapharyngeal extension or prevertebral tissue invasion
- If chemoradiation considered
- CT / MRI recommended
- Thyroid cartilage invasion
- Staging of cervical nodes
Cervical metastases
- N0 neck: No need to image if elective neck dissection planned or for T1 cancers
- N+ neck: Image (U/S or CT) if concern about resectability
Distant metastases: CXR / CT chest: T2 – 4 cancers
Synchronous primary: CXR / CT chest
