Abstract

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.

COVID-19 tanısında göğüs tomografisinin rolü

Abstract

Amaç: COVID-19 hastalığı şüphesiyle hastaneye başvuran hastalarda göğüs bilgisayarlı tomografi (BT)’sinin ‘Klinik Karar’ ve RT-PCR sonuçları ile karşılaştırmalı olarak tanısal gücünü incelemeyi amaçladık.
Gereç ve Yöntem: Bu çalışmaya 11 Mart - 11 Nisan 2020 tarihleri ​​arasında pandemi polikliniğine başvuran, yeni koronavirüs enfeksiyonu şüphesi olan ve aynı anda göğüs BT ve RT-PCR tetkikleri yapılan 162 hasta dahil edildi. COVID-19 tanısı için RT-PCR ve göğüs BT görüntülemenin duyarlılığı, özgüllüğü, pozitif öngörü değeri (PPV), negatif öngörü değeri (NPV), doğruluğu ve pozitif olasılık oranı araştırılmaktadır.
Bulgular: Başvuru sırasında çekilen akciğer tomografilerinin %56,8’inin (92 hasta) viral pnömoni ile uyumlu olduğu bulundu. Altın standart tanı yöntemi olarak kabul ettiğimiz ‘Klinik Karar’ ile hastaların %61,1’i (99 hasta) COVID-19 pozitif olarak değerlendirildi ve tedaviye başlandı. Klinik karara göre göğüs BT’nin duyarlılığı %92,9 idi.
Sonuç: COVID-19 pnömonisi hayatı tehdit eden ciddi bir durumdur. Hızlı tanı ve erken tedavi, mortalite ve morbiditeyi azaltmak açısından çok önemlidir. Göğüs BT erken tanı ve tedavi fırsatı yaratabilir.
