Fig 2. A 48-year-old woman with left floor-of-mouth carcinoma showing a true-negative result for cortical invasion with both MR imaging and CT.
A, Axial T1-weighted MR image (560/14).

Both MR and CT image reveal intact lingual cortex (arrows) adjacent to the tumor mass. Histopathologic examination after marginal mandibulectomy confirmed no tumor invasion into the mandible.
