Lymph node metastasis in head and neck squamous carcinoma: Efficacy of intravoxel incoherent motion magnetic resonance imaging for the differential diagnosis

Highlights • IVIM DWI is feasible in the diagnosis of LN metastasis. • The reduced D values in malignant metastasis lymph nodes reflect the restriction of water diffusion due to hypercellular tissue. • The increased D* values in malignant metastasis lymph nodes reflect the increased blood vessel gen...

Description
Summary:Highlights • IVIM DWI is feasible in the diagnosis of LN metastasis. • The reduced D values in malignant metastasis lymph nodes reflect the restriction of water diffusion due to hypercellular tissue. • The increased D* values in malignant metastasis lymph nodes reflect the increased blood vessel generation and parenchymal perfusion. • The significant TE-dependence effect results in lower f values in malignant metastasis lymph nodes
