We evaluate the feasibility of ultrashort echo time (UTE) imaging in the visualization of sinonasal and skull base bony structures. MRI with UTE imaging are feasible to assess not only the normal bony structures but also diverse anatomic variations of sinonasal cavity and skull base without radiation exposure. This technique may lead to a new application of diagnostic MRI in head and neck imaging and could be expected to prevent additional CT imaging and consequently reduce radiation exposure.
