It's also the most reliable imaging technique for determining if the sinuses are obstructed and the best imaging modality for sinusitis. Use of CT is typically reserved for difficult cases or to define anatomy prior to sinus surgery. The computer workstation that processes the imaging information is in a separate control room. A single Waters' view (occipitomental) appears to provide as much information as the standard four-view series.11, CT scans can provide much more detailed information about the anatomy and abnormalities of the paranasal sinuses than plain films.12 A CT scan provides greater definition of the sinuses and is more sensitive than plain radiography for detecting sinus pathology, especially within the sphenoid and ethmoid sinuses.6,13 CT scan findings can also be quite nonspecific, however, and should not be used routinely in the diagnosis of acute sinusitis.6,14 The primary role of CT scans is to aid in the diagnosis and management of recurrent and chronic sinusitis, or to define the anatomy of the sinuses prior to surgery.2 In many institutions, a limited CT scan costs about the same as a full radiographic series but provides more useful information.2,15,16, A coronal CT image is the preferred initial procedure.
