Title

Evaluation of Chest CT Findings using the Reporting and Data System of Patients with Suspected COVID-19 Infection

  0-0

Abstract

 Background: The simultaneous interpretation of computed tomography (CT) scans performed on patients with suspeCTed clinical signs of coronavirus disease 2019 (COVID-19) or a history of contaCT may accelerate patient isolation, particularly during the peak of the pandemic. The use of an appropriate Scoring system can lead to the conveyance of the findings in a more understandable way and the elimination of differences in interpretations. ObjeCTives: This study aimed to evaluate the diagnostic performance of the coronavirus disease 2019 (COVID-19) imaging reporting and data system (CO-RADS) in admitted patients with suspeCTed COVID-19 infeCTion. Methods: This retrospeCTive study included all patients admitted to our hospital with COVID-19 pneumonia suspicion within March 20-May 15, 2020, who were examined by both CT and real-time reverse transcription polymerase chain reaCTion (rRT-PCR) at initial presentation. Four radiologists, who were blinded to the rRT-PCR results and medical history, assessed all images independently and classified the CT findings according to the CO-RADS previously defined. Diagnostic value of the Scoring system and interobserver agreement in rRT-PCR positive-negative groups and for CO-RADS 1-5 were evaluated. Results: In this study, 274 (153 men and 121 women; 48. 8± 17. 3 years) rRT-PCR positive and 437 (208 men and 229 women; 49. 0± 19. 5 years) rRT-PCR negative individuals were included. It was found that CO-RADS had a good diagnostic performance with area under the receiver operating charaCTeristic roc curve of 0. 857. The sensitivity, specificity, positive prediCTive value, negative prediCTive value, and accuracy were obtained at 81. 9%, 89. 4%, 75. 7%, 92. 5%, and 84. 8%, respeCTively. The interobserver agreement of four radiologists in CO-RADS 1 and 5 was substantial to almost perfeCT according to the kappa values. Other CO-RADS scores showed a fair to moderate agreement. The interrater agreement was slightly higher in the PCR (-) patient group than in the positive one. Conclusion: In conclusion, CO-RADS was a successful Scoring system for distinguishing highly suspicious cases in terms of COVID-19 infeCTion lung involvement, showing high interobserver agreement.
