Figure 26. MRI of a 65-year-old patient with histologically proven squamous cell carcinoma of the nasal cavity.

Figure 26

a) Coronal T1w image. The tumor (x) is iso-intense to muscle, fat tissue is hyperintense on T1w images.

b) Axial T2w image. The tumor is hyperintense to muscle. MRI allows differentiation between hyperintense retention within the maxillary sinus and the tumor.

c) Coronal T2w image with fat suppression. With fat tissue appearing hypointense, tumor and inflammatory changes of the maxillary sinus are better delineated.

d) Coronal contrast-enhanced T1w images with fat suppression. Contrast enhancement is better delineated with fat suppression. The tumor (arrow) enhances avidly but less compared to normal mucosa (arrowhead).
