Mucoceles are usually round hypodense lesions in CT scan commonly associated with sinus wall expansion and erosion (8, 16,18) . detect the presence of inflammatory diseases. Sometimes, the exam table will move during the scan. Prostate Specific Protocol *Schedule at Bremerton Prostate Coil only MRI Shoulder with and without IV Contrast 73223 Inflammation, Infection, Osteomyelitis, . The CT scanner is typically a large, donut-shaped machine with a short tunnel in the center. Safety in X-ray, Interventional Radiology and Nuclear Medicine Procedures, Radiation Therapy for Head and Neck Cancer, evaluate sinuses that are filled with fluid or thickened sinus. The wide variety of different pathologies that can affect the olfactory pathway reflect this complex anatomical relationship. If the exam uses iodinated contrast material, your doctor will screen you for chronic or acute kidney disease. The CT paranasal sinus protocolserves as an examination for the assessment of the study of the mucosa and bone system of the sinonasal cavities. 200 Hawkins Drive

You will be alone in the exam room during the CT scan, unless there are special circumstances. However, the technologist will always be able to see, hear and speak with you through a built-in intercom system. There was no seasonal variation to his symptoms, and allergy testing was negative. A major advantage of CT is its ability to image bone, soft tissue, and blood vessels all at the same time.

COMPUTED TOMOGRAPHY (CT) - SINUSES Computed tomography (CT) of the sinuses uses special x-ray equipment to evaluate the paranasal sinus cavities - hollow, air- filled spaces within the bones of the face surrounding the nasal cavity. Air appears black. Better surgical outcome by image-guided navigation system in endoscopic removal of sinonasal inverted papilloma. Balloon sinus surgery performed in-office with the Nuvent EM Sinus Dilation System is a minimally invasive procedure to open and drain blocked sinuses.

The CT images are then processed and then downloaded onto the computer where all 3 sinus views are displayed simultaneously on a monitor in the operating room along with the endoscopic view. After the ostiomeatal complex is accessed through the nostril with a rigid endoscope, the ostia and recesses are targeted, depending on the location and pattern of disease. `l\/ c+f>@@@@@V &x&p'@@@@@sb++ The IGS serves as a useful tool in assisting with difficult areas, but the system itself is inherent to built in and user error. The preferred initial procedure is a coronal CT image (13). Advances in diagnostic imaging techniques (e.g., computed tomographic [CT] scan and magnetic resonance imaging [MRI]) have enhanced the understanding and management of sinusitis. `l\/ c+f>@@@@@V &x&p'@@@@@MlP_TEc+ kr>R8 N+[LW{ Medtronic Operational Headquarters 710 Medtronic Parkway Minneapolis, MN 55432-5640 USA, Central/Eastern Europe, Middle East & Africa, Electromagnetic Compatibility Guide for Cardiac Devices, American Academy of Otolaryngology Head and Neck Surgery (AAO-HNS), American Academy of Otolaryngology - Head and Neck Surgery (AAO-HNS).

They should not have repeated CT exams unless necessary.
It is used occasionally in cases of suspected tumors or fungal sinusitis.1719 Otherwise, MRI has no advantages over CT scanning in the evaluation of sinusitis. Image-guided surgery (IGS) is the use of a real-time correlation of the operative field to a preoperative imaging data set that reflects the precise location of a selected surgical instrument to the surrounding anatomic structures. His ears were clear by otoscopy, and his nasal examination revealed a right-sided septal deviation.
