30 paź 2020 · Dynamic contrast-enhanced MRI perfusion imaging can be of value in detecting and quantifying a microvascularity within tissue, providing characterization for head and neck cancers. This is used to generate blood flow, blood volume, and transit time parameters within areas of interest, and may help in assessing the histological grade of tumors.

Cross-sectional imaging has a central role to play in the management of patients with malignant disease and is used at all points along the patient care pathway: In the initial diagnosis and the staging of disease extent. For monitoring response to treatment. For evaluation of any residual mass after treatment.
MRI is generally the cross-sectional study of choice for tumours of the suprahyoid neck, although local operational policy will dictate its role in imaging the various tumour sites. Multislice computed tomography (MDCT) may be used to acquire a rapid, high spatial resolution volume of data.
