![]() PET/CT : This nuclear medicine exam combines positron emission tomography (PET) and CT scans to create images that pinpoint the anatomic location of abnormal metabolic activity.Cone beam CT is generally used to confirm that radiation treatments are correctly targeted. Dental Cone Beam CT: This type of CT scan uses special technology to generate three dimensional (3-D) images of dental structures, soft tissues, nerve paths and bone in the craniofacial region in a single scan.It can help reveal the presence of oral cancers. Panoramic Dental X-ray: Also called panoramic radiography, this two-dimensional (2-D) dental x-ray examination captures the entire mouth in a single image, including the teeth, upper and lower jaws, surrounding structures and tissues.Much like CT of the sinuses, CT of the head can help detect abnormalities of the paranasal sinuses and nasal cavity. It is primarily used to detect cancers of the sinuses and nasal cavities and plan for surgeries. The cross-sectional images generated during a CT scan can be reformatted in multiple planes and can even generate three-dimensional (3-D) images. This diagnostic medical test produces multiple images or pictures of a patient's paranasal sinus cavities. Currently, MRI is the most sensitive imaging test of the head in routine clinical practice. Head MRI: During head MRI, a powerful magnetic field, radio frequency pulses and a computer will be are used to produce detailed pictures of the inside of the head and neck. ![]() With the aid of topical anesthesia, the tube is inserted into the mouth or nose to take pictures and evaluate the abnormal cells. Nasopharyngolaryngoscopy: This endoscopy exam uses a flexible, illuminated optical instrument called an endoscope to examine the nasal cavity, voice box and throat.Your doctor may order one or more of the following imaging tests to help determine if you have a cancer and whether it has spread: Your doctor will ask you about your medical history, risk factors and symptoms and perform a physical exam.

Ethnicity, especially of Asian descent (nasopharynx cancer).Head and neck cancer is more likely to happen in adults over the age of 50 and is twice as likely to occur in men. These cancers are grouped together due to their location and because head and neck surgeons – also known as otolaryngologists or ear, nose and throat (ENT) physicians – are almost always members of the oncology team managing head and neck cancer patients. Head and neck cancer is a group of cancers that usually start in the squamous cells lining the mouth, voice box (larynx), throat (pharynx), salivary glands, nasal cavity and paranasal sinuses.
