CT scan can show the full extent of the polyp, which may not be fully appreciated with physical examination alone. Imaging is also required for planning surgical treatment. [7] On a CT scan, a nasal polyp generally has an attenuation of 10–18 Hounsfield units, which is similar to that of mucus. Nasal polyps may have calcification. [14]
Other ways to clear mucus from your nose. While blowing your nose is one of the easier ways to clear it out, there are other things you can do to reduce your congestion. Be sure to consult your ...
A CT scan showing evidence of the nasal cycle: the more patent airway is on the right of the image, the swollen turbinates congesting the left. The nasal cycle is the subconscious [1] [2] alternating partial congestion and decongestion of the nasal cavities in humans and other animals. This results in greater airflow through one nostril with ...
An MRI using flow parameters and an MR venogram are more sensitive than a CT scan and are the imaging studies of choice to diagnose cavernous sinus thrombosis. Findings may include deformity of the internal carotid artery within the cavernous sinus, and an obvious signal hyperintensity within thrombosed vascular sinuses on all pulse sequences.
A turbinectomy or turbinoplasty (preserving the mucosal layer) is a surgical procedure, that removes tissue, and sometimes bone, of the turbinates in the nasal passage, particularly the inferior nasal concha.

CT scan in the coronal plane, showing the ostiomeatal complex (green area) The lateral wall of each nasal cavity mainly consists of the maxilla . However, there is a deficiency that is compensated for by the perpendicular plate of the palatine bone , the medial pterygoid plate , the labyrinth of ethmoid and the inferior concha .
