Newer imaging techniques in head and neck cancer

Abstract

Computerized tomography (CT), Magnetic Resonance Imaging form the backbone of head and neck cancer imaging. This review describes the role of newer functional imaging techniques like diffusion weighted MR imaging and perfusion imaging in head and neck cancers. A review of the current role of PET-CT in head and neck tumors is also included in this article.

“…Necessary screening programs for people at high risk (smokers and/or heavy drinkers) or in the posttherapeutic phase for recurrence detection are key factors for prognosis and are difficult to implement and sustain. The posttherapeutic phase of recurrence detection is standardized in most countries and essentially based on, besides clinical examination, the diagnostic sensitivity of imaging such as magnetic resonance imaging, computed tomography, or one of those coupled with positron emission tomography 6‐9 . Blood‐related biomarkers, such as circulating tumor cells or cancer‐related metabolites, are still under investigation.…”

“…The posttherapeutic phase of recurrence detection is standardized in most countries and essentially based on, besides clinical examination, the diagnostic sensitivity of imaging such as magnetic resonance imaging, computed tomography, or one of those coupled with positron emission tomography. [6][7][8][9] Blood-related biomarkers, such as circulating tumor cells or cancer-related metabolites, are still under investigation. Biochemical diagnosis of tumor-specific factors (so-called tumor markers) is of great interest, but in tumors of the head and neck area, to date they have no relevance in the clinical routine.…”
