Table 2.

Interpretability of the sequences T1, T2, TIRM, and DWI for the following anatomical structures: ipsilateral and contralateral orbit, maxillary and frontal sinus (ipsilateral and contralateral), ethmoidal cells, sphenoid sinus, clivus, and nasopharynx.

We established four different categories. Category 1 (green): clear evaluation is possible. Category 2 (yellow): mild to moderate limitations are present. Category 3 (orange): considerable limitations exist. Category 4 (red): no interpretability, as the image is entirely obscured by artifacts.
