The subspecialty concerned with the diagnostic radiology of diseases of the head and neck including the brain, bones, muscles, blood vessels, nerves, glands, nose, mouth, teeth, tongue, and throat.
The anatomy in this region is very complex, and interpretation in diagnostic imaging is challenging in many ways. CT has been widely used for tumour detection and in precise examination of the paranasal sinuses. MRI and PET are nowadays the state of the art in tumour imaging.

Ultrasound can also detect mass lesions in other structures including enlarged lymph glands and is used as a guide for biopsy.
