Summary
Screening coronal CT scans are now standard for sinus pathology, replacing sinus series. Complete coronal CTs are used for visible mucosal disease, with axial views and bone windows being routine.
Area of Science:
- Radiology
- Otolaryngology
Background:
- Sinus series X-rays were historically used for initial sinus pathology evaluation.
- Computed tomography (CT) offers more detailed anatomical visualization.
Purpose of the Study:
- To describe the current institutional practice for imaging patients with suspected sinus pathology.
- To outline the indications for different CT scan protocols.
Main Methods:
- Retrospective review of imaging protocols for suspected sinus pathology.
- Coronal and axial CT scan parameters and window settings were analyzed.
- Comparison of screening coronal CT with sinus series and complete coronal CT.
Main Results:
- Screening coronal CT has largely replaced the sinus series for initial evaluation.
- Complete coronal CT is obtained when endoscopic examination reveals obvious mucosal disease.
- Axial CT scans are not routinely performed, and bone windows are consistently used.
Conclusions:
- The institutional imaging protocol prioritizes coronal CT for sinus pathology.
- Specific CT protocols are tailored based on clinical and endoscopic findings.
- Standardization of CT viewing parameters (bone windows) aids in evaluating bony structures.
