Aim: We aimed to examine the diagnostic power of chest computerized tomography (CT) comparing with ‘Clinical Decision’ and RT-PCR results among the patients admitted to the hospital with COVID-19 disease suspicion. Material and Method: This study included 162 patients who applied to the pandemic outpatient clinic between March 11 and April 11, 2020, suspected of new coronavirus infection, and had chest CT and RT-PCR tests at the same time. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), accuracy and positive odds ratio of RT-PCR and chest CT imaging are investigated for the diagnosis of COVID-19. Results: It was found that 56.8% (92 patients) of chest CT scans taken at admission were compatible with viral pneumonia. With the ‘Clinical Decision’, which we accept as the gold standard diagnostic method, 61.1% of the patients (99 patients) were evaluated as COVID-19 positive and treatment was started. According to clinical decision, sensitivity of chest CT was 92.9%. Conclusion: COVID-19 pneumonia is a serious life-threatening condition. Rapid diagnosis and early treatment are very important in terms of reducing mortality and morbidity. The chest CT might create an early diagnosis and treatment opportunity. |
