How do they do a nasal CT scan?
You will be asked to lie on a narrow table that slides into the center of the CT scanner.
You may lie on your back, or you may lie face-down with your chin raised.
Once you are inside the scanner, the machine's x-ray beam rotates around you.
You will not see the rotating x-ray beam..
What is a CT of the head of the sinuses?
A CT of the Sinuses is an exam that takes very thin slice (3.5mm) images of all four sinus cavities: frontal, ethmoid, maxillary, and sphenoid.
This allows a more accurate diagnosis of conditions such as sinusitis, polyps, deviated septums and congenital defects..
What is a nasal CT scan used for?
A computed tomography scan (CT or CAT) of your sinuses uses X-ray technology and advanced computer analysis to create detailed pictures of the sinus.
A CT of the sinus can help your physician to assess any injury, infection or other abnormalities..
What is computed tomography of the nose?
CT Sinuses.
Computed tomography (CT) of the sinuses uses special x-ray equipment to evaluate the paranasal sinus cavities – hollow, air-filled spaces within the bones of the face surrounding the nasal cavity.
CT scanning is painless, noninvasive and accurate..
What is ENT CT scan?
It is the most reliable imaging technique for sinuses and other structures within the ear, nose, and throat regions.
CT scans benefit our ENT providers in evaluating and diagnosing chronic sinusitis, dizziness, certain ear and throat conditions, and more..
What is the difference between a CT scan and a nasal endoscopy?
Compared to CT Scan, nasal endoscopy can even detect subtle changes like mucosal hypertrophy, inflammation, erythema, pathologic secretions even before radiographic changes happen.
It can differentiate between infective, inflammatory and allergic diseases..
What is the position for a CT scan of the sinuses?
For a CT scan of the sinuses, the patient is most commonly positioned lying flat on the back.
The patient may also be positioned face-down with the chin elevated.
Straps and pillows may be used to help the patient maintain the correct position and to hold still during the exam..

A computed tomographic scan of paranasal sinus is useful in visualizing areas not accessible by routine endoscopy..
Why would ent order a CT scan?
A CT of the sinuses may be ordered for a variety of reasons.
We commonly use this form of imaging to evaluate complaints of snoring, congestion, ear and/or breathing problems.
The CT scan can be used to show: Structural abnormalities such as a deviated septum, nasal polyps, or concha bullosa..
- CT scanning of the sinuses is primarily used to: Help diagnose and manage chronic or recurrent acute sinusitis.
Detect inflammation or infection, even in deep areas that would be missed by nasal endoscopy or x-ray. - CT technical factors are optimized with scanning in the prone position with thin (3-mm) sections obtained through the anterior paranasal sinuses.
This allows optimal visualization of the ostiomeatal unit. - It is the most reliable imaging technique for sinuses and other structures within the ear, nose, and throat regions.
CT scans benefit our ENT providers in evaluating and diagnosing chronic sinusitis, dizziness, certain ear and throat conditions, and more.
