Nose CT scan
Computed tomography (CT) is a medical imaging method using X-ray tomography created by computer processing. It provides important diagnostic information in various anatomical planes. Conventional sinus X-rays are not really helpful, as various anatomical structures superimposed on one another prevents proper assessment of the ethmoid sinuses and ostiomeatal complex regions.
The main advantage of CT over MRI scanning is that it demonstrates bone as well as soft tissue features, and is therefore the radiological assessment of choice in patients with sinus problems
The scanning techniques involves lying still with the head in a medical “hair-dryer” open capsule for approximately 20 minutes. It is a completely painless procedure.
