Diffusion tensor imaging of oral carcinoma: Clinical evaluation and comparison with histopathological findings.

Purpose: This study aims to assess the usefulness of diffusion tensor imaging (DTI) as a noninvasive method for the evaluation of histological grade and lymph node metastasis in patients with oral carcinoma (OC).

Materials And Methods: Thirty-six consecutive patients with histologically confirmed OC underwent examination by 3-T MRI. DTI was performed using a single-shot echo-planar imaging sequence with b values of 0 and 1000 s/mm and motion-probing gradients in 12 noncollinear directions.
