Value of a contextual template for preoperative sinus CT Value of a contextual template for preoperative sinus CT. A, Axial contrast-enhanced fat-suppressed T1-weighted image shows diffuse paranasal sinus opacification, with nonenhancement in the right sphenoid sinus (arrow), compatible with invasive sinusitis. Value of a contextual template for preoperative sinus CT. A, Axial contrast-enhanced fat-suppressed T1-weighted image shows diffuse paranasal sinus opacification, with nonenhancement in the right sphenoid sinus (arrow), compatible with invasive sinusitis. Preoperative sinus CT imaging was performed (B) and shows a dehiscent right carotid canal (arrow) that could have been overlooked without a contextual template (C). Remembering all the sinus variants can be difficult, but a contextual template can aid in this dilemma by providing a checklist approach. To improve education and usage of this template, a hyperlink can be added to the dictation software with imaging examples showing these sinonasal variants. M.D. Mamlouk et al.
