Can perfusion sensitized MR diffusion weighted imaging discriminate between benign and malignant nodes for patients with head and neck squamous cell carcinoma?
Objective: To investigate fast (perfusion sensitized) and slow (true diffusion sensitized) apparent diffusion coefficient (ADC) measurements as discriminators of benign from malignant lymph nodes in patients with head and neck (H&N) squamous cell carcinoma (SCC). Materials and Methods: Seventeen patients with H&N SCC staged for nodal disease using anatomical MRI, contrast enhanced CT and ultrasound ± fine needle aspiration gave informed consent for additional MR diffusion weighted imaging (DWI). Axial DWI was performed by short tau inversion recovery (STIR) echo planar imaging and trace weighted images obtained b 0, 50, 100, 300, 600 and 1000. Apparent diffusion coefficient (ADC) was calcul…
