Sinus CT

With the latest technology and the most up-to-date training, the Dallas Sinus Center can diagnose sinus problems with state-of-the-art Sinus CT scan.


What does a Sinus CT show?


The best image of the sinuses can be obtained with a CT (computer tomography) scan. CT scans allow the physician to examine the sinuses in detailed cross-sections and detect inflammatory diseases, evaluate fluid-filled sinuses or thickened sinus membranes, and diagnose sinusitis. Physicians can also use CT scans to plan for surgery by defining anatomy or giving further information about tumors of the nasal cavity and sinuses.

The interior of the sinuses, which often cannot be seen on endoscopy unless the patient has had prior surgery, can be viewed on the CT scan images. If desired, the sinuses can be imaged in more than one angle to obtain images from above, side or front views. There are also office-based and operating room-based computers that allow the reconstruction of additional planar views and even 3-D reconstructions that may allow for more detail and better surgical planning. These types of scans are often called navigational scans. They allow the CT scan images to be displayed during surgery as a system which can track the location of the surgical tools inside the nose when overlaid upon the x-ray images. These types of scans can be very useful for more difficult cases or in cases where prior surgery and scar tissue or disease may have changed the usual landmarks inside the nose.


How is a Sinus CT different than an MRI?


Unlike getting an MRI, patients rarely feel claustrophobic because the scanner has no enclosures. The scan is painless and takes less than 10 minutes. There are now miniature-CT scanners that are less intimidating in appearance and only require a few minutes to obtain a full sinus examination.
