Review the characteristic findings and indications for computed tomography (CT) of the brain and neck Discuss advantages of dual energy (DE)/spectral CT in adding to the clinical utility of CT in head and neck imaging

Indications for CT of the brain and neck Intra/extracranial vessel stenosis and aneurysms Intracranial haemorrhage Intracranial and neck masses Principles, technical aspects, and physics of DE/spectral imaging Clinical applications of DECT Radiation dose reduction Improved bone/plaque removal reconstructions Plaque analysis Differentiating iodine from haemorrhage post thrombolysis Greater grey/white differentiation and reduction of beam hardening artifacts in the posterior fossa Material quantification of abnormal enhancement neoplasms Clinical utility evaluating/staging neck masses Current limitations of DE/spectral CT in head and neck imaging Cases of DE/spectral CT imaging of the brain, intra/extracranial vessels, and neck from our institution with a discussion of characteristic findings and clinical applicability

CT is valuable in many indications in head and neck imaging DECT has significant clinical advantages over single energy CT in the evaluation of the brain, neck, and intra/extracranial vessels
