“…The sensitivity of the ten-slice CT in the frontal, ethmoid, maxillary and sphenoid sinuses was 80, 90, 93 and 94% respectively. Our findings are identical to Hagtvedt et al (2) because of similar protocol and significantly higher than Awaida et al (4) because of interpretation 6 more slices. Reducing the radiation dose of CT would enable more common usage of this technique for screening rhinosinusitis.…”

“…Failure to identification of sinusitis can lead to significant complications such as cellulitis and osteomyelitis. The indication and the necessity for plain X-rays in diagnosis and further management of sinusitis has declined over the last decade (4, 7). Conventional X-ray findings are correlated with operative finding only in half of the patients with sinusitis (3).…”

“…Many studies have demonstrated that decreasing the number of CT slice results in lower cost and less radiation exposure (3). Authors have shown that limited CT techniques are comparable to contiguous paranasal CT for diagnosing rhinosinusitis but limited protocols have proven insufficient for surgical planning (2-4). …”

“…Awaida et al used a similar four-slice protocol with sensitivity and specificity of 81 and 89% respectively, for detecting rhinosinusitis in any sinus (4). Cagici et al used a three- slice protocol with sensitivity and specificity of 95.1 and 92.6% respectively.…”

BackgroundParanasal sinus CT has high sensitivity and specificity for sinusitis. However, this modality is costly and involves greater radiation exposure than plain radiographs.ObjectivesWe tried to compare 10-cut limited CT scan and standard CT scan in the diagnosis of sinusitis.Materials and MethodsWe conducted a cross sectional case series from August to December 2010 on 150 patients with non-randomized sampling method in academic hospitals related to medical school of Shahid Beheshti University of medical sciences. Using standard CT scan as the gold standard, the sensitivity and specificity of limited series were calculated for each sinus group.ResultsIn our study limited CT scan had a sensitivity of 92%, specificity of 94%, positive predictive value of 90% and negative predictive value of 95%.ConclusionsThe limited CT scan is useful for confirming the clinical diagnosis of sinusitis.

Plain sinus radiography is the imaging technique most frequently used to investigate suspected rhinosinusitis, but it has low diagnostic sensitivity. Contiguous paranasal computerized tomography (CT) gives detailed information about the pathology, anatomy and anatomical variations of the paranasal sinuses, but this method also has limitations. The cost of using this technique for all cases of suspected rhinosinusitis is prohibitive, and complete CT scans involve considerable radiation exposure. The aim of this study was to devise a CT protocol for diagnosing and following rhinosinusitis that is more economical and involves much less radiation exposure than contiguous CT. In this retrospective study, three physicians independently reviewed the contiguous coronal paranasal CT studies of 136 patients. The study population comprised the adult patients who were investigated for suspected chronic rhinosinusitis. All scans had been obtained at the second visit, after the patient had completed a 3-week course of medical treatment. For each case, the same three slices were selected to form the "three-slice CT" exam, and the same physicians independently evaluated this set. Using the results from the contiguous set as the gold standard, we calculated the sensitivity and specificity of three-slice CT for identifying rhinosinusitis. The sensitivity and specificity of three-slice CT for identifying inflammatory sinus disease were 95.1 and 92.6%, respectively. Three-slice CT is a valuable method for diagnosing and following rhinosinusitis cases, and would be cheaper and involve less radiation exposure than contiguous coronal CT. However, despite the high cost and greater radiation exposure, contiguous CT remains the gold standard for evaluating detailed sinus anatomy and disease progression.

Abstract: The limited sinus CT scan is superior to plain radiographs but is not as good as the full CT scan in the evaluation of sinusitis.
