Abstract

Aim
CT has an important place in diagnosing SARS-CoV-2 due to the RT-PCR test's high false-negative rate and the faster evaluation of CT, although the RT-PCR test is the gold standard. This study aims to understand chest CT features and distributions in patients with SARS-CoV-2 proven by RT-PCR.
Materials and Methods
This study is retrospective and includes one hundred adult patients with confirmed SARS-CoV-2 infection who admitted to the hospital. The Chest CT findings of these patients were retrospectively recorded. Radiological Society of North America reporting guidelines for SARS-CoV-2 pneumonia was referenced to classify chest CT findings.
Results
In SARS-CoV-2 patients confirmed by RT-PCR, the mean age of 79 pneumonia patients (54.0216.99) was higher than age of patients without pneumonia (42.4717.78). Prevalences of ground-glass opacity, consolidation, posterior dominance, bilaterality, peripheral distribution, multifocality, vascular enlargement, pleural effusion, lymphadenopathy, tree-in-bud pattern, halo sign and reverse halo sign were 74.68%, 3.79%, 17.72%, 43.03%, 70.88%, 84.81%, 84.81%, 12.65%, 2.53%, 1.26%, 2.53%, 8.86%, and 3.79%, respectively.
Conclusion
This study's findings indicate that common chest CT findings in SARS-CoV-2 pneumonia are ground glass opacities with multifocal, multilobar, peripheral and bilateral involvement. No significant result was shown in favor of posterior or lower lobe dominance. According to the present study, SARS-CoV-2 patients are more likely to get pneumonia as they get older.

SARS-COV-2 PNÖMONİSİNDE TORAKS BT ÖZELLİKLERİ

Abstract

Amaç
SARS-CoV-2’nin tanısında; altın standartın RT-PCR testi olmasına ragmen, RT-PCR testinin yüksek yalancı negatiflik oranı ve BT!nin daha hızlı sonuç vermesi nedeniyle, BT de önemli bir yere sahiptir.Bu çalışmanın amacı RT-PCR ile kanıtlanmış SARS-CoV-2 hastalarında toraks BT özelliklerinin ve dağılımının değerlendirilmesidir.
Gereç ve Yöntem
Bu çalışmaya hastaneye başvuran, SARS-CoV-2 tanısı RT-PCR ile doğrulanan, 100 yetişkin hasta dahil edilmiştir. Bu hastaların toraks BT bulguları retrospektif olarak kaydedilmiştir. BT bulguları, Kuzey Amerika Radyoloji Topluluğu tarafından SARS-CoV-2 için yayınlanan klavuza göre değerlendirilmiştir.
Bulgular
RT-PCR ile doğrulanan 100 SARS-CoV-2 hastasının, 79’unda pnömoni mevcut olup yaş ortalaması (54.0216.99) iken pnömoni bulgusu olmayan 21 hastanın yaş ortalaması (42.4717.78) olarak bulunmuştur. Buzlu cam dansitesi, konsolidasyon, posterior ağırlıklı tutulum, bilateral tutulum, periferik dağılım, multifokalite, vasküler genişleme, plevral efüzyon, lenfadenopati, tomurcuk ağaç paterni, halo işareti ve ters halo işareti prevalansları sırasıyla % 74,68,% 3,79,% 17,72, % 43.03,% 70.88,% 84.81,% 84.81,% 12.65,% 2.53,% 1.26,% 2.53,% 8.86 ve % 3.79 olarak bulundu.
Sonuç
SARS-CoV-2 pnömonisinde sık görülen göğüs BT bulguları multifokal, multilobar, periferik ve bilateral tutulumlu buzlu cam opasiteleridir. Posterior ya da alt lob hakimiyeti lehine anlamlı sonuç gösterilememiştir. Bu çalışmaya göre, SARS-CoV-2 hastalarının yaşlandıkça pnömoni olma olasılığı artmaktadır.
