The process of taking a CT of the sinus cavities begins by taking many different X-ray views at various different angles, which are then combined with the use of computer processing to create cross-sectional images of the bones and soft tissue inside of your body, including tissues inside of solid organ. Ordinary X-ray testing does not show clear images of soft tissue, so doctors often request CT scanning to get a good image of soft tissue including organs, muscles, blood vessels, nerves, and the brain. Sometimes a contrast dye is used as it shows up clearer on the screen.
A quality CT scan of the sinuses will display the facial structures, including the patient’s four pairs of sinuses connected to the nasal sinus cavity.
Reasons for a Sinus CT scan:
CT scans are used for a multitude of reasons. They may be done to check for certain cancers in various different ways including to detect abnormal tumors, growths or lumps. They also identify the location of tumors, the stage of cancer, and where to perform a biopsy.
A sinus CT scan can be used to guide doctors or surgeons during a procedure, such as a biopsy. They are important in planning for certain types of therapy and surgery, as well as in the aftermath to determine whether the patient’s body is responding to treatment.
CT scans can be used to detect cysts or infections in the body. They can also identify the bone structures within the body and can accurately measure the density of bone.
A CT scan is often used to quickly inspect a patient after an accident in order to identify traumatic internal injuries.
A Sinus CT scan may help diagnose (find):
A sinus CT scan may help diagnose sinusitis.
A CT scan of the sinuses can detect inflammatory diseases and evaluate fluid filled sinus membranes.
A sinus CT can help doctors plan for surgery both before and after.
A sinus CT test may also show birth defects in the sinuses, infections in the bones of the sinuses (osteomyelitis), reveal injury to the face over the sinuses.
The cause of repeated bloody noses (epistaxis), a irritating sinus infection, sinusitis or other sinus infections can also be diagnosed with the help of a quality sinus CT. In some cases, masses, tumors, and/ornasal polyps can be found.
