A 65-year-old man with SCC. A, Axial T1-weighted MR image (TR/TE = 500/15 ms) shows tumor with homogeneous signal intensity occupying the right maxillary sinus and extending into the surrounding bony structures. B, Axial FS (SPAIR) T2-weighted MR image (TR/TE = 6385/80 ms) shows tumor with heterogeneous signal intensity. C, Axial contrast-enhanced T1-weighted MR image (TR/TE = 500/15 ms) shows tumor with peripheral enhancement. D, Axial color ADC map shows tumor with a low ADC. Overall ADC = 0.8 × 10−3 mm2/s. Areas with extremely low, low, intermediate, and high ADCs occupy 17%, 78%, 5%, and 0%, respectively, of the tumor.
