ct sinus landmark protocol

Although mucosal thickening is seen in more than 90 percent of sinusitis cases, it is very nonspecific.68 Air-fluid levels and complete opacification are more specific for sinusitis but are seen in only 60 percent of sinusitis cases.6 Interpretation of plain radiographs can vary widely among different observers, and there is a high rate of false-negative results.2,9, Radiographs of the sinuses in infants aged three years or younger are not useful because of false opacification from undeveloped sinuses.10 Other important limitations of plain radiographs include poor visualization of ethmoid air spaces and difficulty differentiating between infection, tumor, and polyp in an opacified sinus.2, Because clinical judgment is sufficient to diagnose sinusitis in a majority of cases, and empiric treatments are inexpensive and safe, only a small percentage of patients who develop recurrent or complicated sinusitis are candidates for imaging studies. Note: we are unable to answer specific questions or offer individual medical advice or opinions. With pediatric patients, a parent may be allowed in the room but may need to wear a lead apron to minimize radiation exposure. When the exam is complete, the technologist will ask you to wait until they verify that the images are of high enough quality for accurate interpretation by the radiologist. `l\/ c+f>@@@@@V &x&p'@@@@@MlP_TEc+ kr>R8 N+[LW{ The computer workstation that processes the imaging information is in a separate control room.

Women will need to remove bras containing metal underwire. 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. 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.

Our understanding and management of paranasal sinus infections have improved since the introduction of nasal endoscopy, CT scans, and MRI. 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. Alternative Names. The endoscopic view obtained of the surgical field and positioned instrumentation should be the primary focus while performing the surgery. He also had a large air cell (i.e., con-cha bullosa) within the left middle turbinate, which likely contributed to obstruction of ostia draining adjacent sinuses (Figure 1, part B).
