TEACHING POINTS
Advanced cross-sectional imaging plays a critical role in providing differential diagnoses, treatment decisions, and prognostic implications in head and neck infections. Contrast-enhanced CT is the imaging modality of choice for head and neck infections; however, other imaging modalities may be complementary and diagnostic. MRI is excellent for evaluation of intracranial spread of inflammation/abscess formation and osteomyelitis, etc. DWI and ADC values are useful in providing differential diagnoses and evaluating treatment response of head and neck infections. 18F-FDG-PET/CT is helpful in the follow-up of skull base osteomyelitis. Dual energy CT allows for various techniques such as metal artifact reduction and material decomposition imaging that can help reduce dental metal artifacts, increase salivary stone detection. Metal artifact reduction algorism can help reduce dental metal artifacts. Subtraction CT techniques are used to reduce dental metal artifacts and detect destructive osseous changes. This presentation will provide an overview of must-know head and neck infections with updated advanced imaging techniques and their imaging findings.
