Abstract

Background and purpose: Coronal CT scan of paranasal sinuses with contiguous images is the gold standard technique in diagnosis of SINUSITIS. Considering the expense and high dose of radiation in conventional CT scan, clinical measurements and simple radiography is not enough sensitive and specific, some workers have suggested limited screening (non contiguous) instead of conventional CT image. This study compared the diagnostic accuracy of coronal CT with limited screening (4 screens) to conventional CT in diagnosis of SINUSITIS.Materials and methods: On 100 patients suspected of SINUSITIS referred to Emam Khomeini hospital. Coronal CT scan (with 16 screens) was performed. And on the basis of relevant scout view, four images of limited screenings (non contiguouse images) were selected and printed. Images of the both CT techniques were reported seperately by two radiologists. (Totally, four CT reports for each patients were given) The results of standard and limited screening CT reports given from the first radiologist were compared with the reports of the same, given by the second radiologist.Results: The comparitive results for the standard and limited screening techniques reported by two radiologists referred to as kappa value were 0.95 and 0.97 respectively. Which indicate a good aggreement between two radiologists in giving the reports of the images. Limited screening technique generally had the rate of 94.1% and 93.5% for sensitivity and accuracy respectively. General prevalence of SINUSITIS in the patients under study was 67%. Maxillar sinus was the most involved one with result of 98.7%.Conclusion: Limited screening CT technique for paranasal sinuses can be a proper technigue as a first evaluative measurement in the patients suspected for SINUSITIS. For this, can replace simple radiography. Advantage of this technique can be due to use of less dose of radiation, more speed of radiography and less expenses.
