What is sinus CT scan?
sinus CT scanning is a imaging test that uses advanced X -ray technology to create a detailed image of cavities, hollow passages of the vague functions that are located in the skull. The purpose of the sinus CT scan is usually helping doctors in diagnosing a health condition involving a cavity, such as chronic sinusitis, cysts, polyps, etc. During this usually a short procedure, the patient is very still on a moving table that then slipped into the scanning facility. As with all CT scans, sinus CT scan exposes patient radiation and is usually ordered only for those who have serious or long -term sinus problems.
During the sinus CT scan, the scanner acquires a series of X -ray images of the patient's head, which then connects through a computer to create a detailed illustration of the patient. Because it is impossible to see the cavities with the naked eye, this type of scan can be very useful in identifying a difficult to diagnose sinuspos. MayLad to show that sinus or bone surrounding the sinus have been infected. Alternatively, it may reveal that structural abnormality or growth, such as a tumor or cyst, causes sinus blocking. Once the doctor has verified or excluded the presence of sinus through this type of scanning, it can create a suitable treatment plan.
Normally the completion of sinus CT scan takes about 15 minutes. During this time, the patient must lie motionlessly on the sliding table. The table is slipped into the scanning mechanism that captures a number of X -ray images of the head. These images can be printed or studied on the computer screen. Metal objects such as jewelry or hairpins cannot be worn during scanning because they can affect the quality of the images created by the scanner.
as well as all imaging tests that use X -rays, sinus ct scan briefly reveal indiviidual tested on radiation, which canthat increase the risk of cancer. As a result, most doctors avoid the arrangement of this test if the patient's cavity problems do not seem to be critical, or if its condition has repeated or has not responded to several forms of treatment. However, many medical experts argue that the level of radiation exposure associated with this procedure is so small that the potential benefits of convincing diagnosis of the patient's sinus condition outweigh the risks of the procedure.
