Like traditional x-rays, it produces multiple images or pictures of the inside of the body. The anatomy will certainly change with the progression of the procedure. He appeared healthy on examination and had hyponasal speech. Persistent or progressive symptoms after maximal medical therapy, in combination with CT evidence of paranasal sinus disease, should prompt referral. If you suffer from chronic sinusitis, hearing loss, or ear infections, your ENT may order a CT scan of the sinuses or temporal bones to visualize the area and obtain the information necessary to create a comprehensive and effective treatment plan.

Interpreting findings seen at CT of the neck is challenging owing to the complex and nuanced anatomy of the neck, which contains multiple organ systems in a relatively small area. CT is beneficial in studying chronic disease of the paranasal sinuses, not least to assess whether it has spread to surrounding structures. Acute Stroke - Brain. After this treatment, his symptoms improved approximately 50 percent, and he received a limited CT scan of the sinuses. If neoplasia is suspected, the use of an intravenous contrast medium is indicated. Uncomplicated cases of sinusitis are most often treated empirically based on findings from the history and physical examination. In addition, in the case of planned surgery, imaging can provide the surgeon with necessary information regarding any anatomical variants and allow the diagnosis of clinically silent diseases, e.g. 150 to 400 HU). Int Forum Allergy Rhinol. Referral will occasionally be needed in unusual or complicated cases. Rotating around you, the x-ray tube and electronic x-ray detectors are located opposite each other in a ring, called a gantry. The risk of serious allergic reaction to contrast materials that contain iodine is extremely rare, and radiology departments are well-equipped to deal with them. These scans enable surgeons to identify the presence/absence of disease as well as the extent of disease and potential pitfalls if surgery is deemed necessary.
