Abstract:

Early detection and qualitative diagnosis of head and neck lymphadenopathy is very important, which is helpful for timely clinical intervention and treatment plan formulation, delaying or stopping disease progression. At pre-sent, multiple sets of dual-energy CT images, such as virtual non-contrast image, iodine map, virtual monoenergetic ima-ges, spectral Hounsfield unit attenuation curves and blended images have been gradually used to evaluate the head and neck lymph node lesions, providing many quantitative indicators for the qualitative, staging and pathological classification of lymph node lesions. This article reviews the research progress of multi-group post-processing images and related parameters of dual-energy CT in the evaluation of cervical lymph node diseases.

Key words: cervical lymph node, cervical lymph node enlargement, dual-energy CT, head and neck imaging
