Maximilian Schulze-Hagen,Christian Hübel,Michael Meier-Schroers,Can Yüksel,Anton Sander,Marwin Sähn,Michael Kleines,Peter Isfort,Christian Cornelissen,Sebastian Lemmen,Nikolaus Marx,Michael Dreher,Jörg C. Brokmann,Andreas Kopp,Christiane K. Kuhl +14 more
TL;DR: In patients with symptoms compatible with CO VID-19, LDCT can esablish the diagnosis of COVID-19 with comparable sensitivity to RT-PCR testing, and offers a high specificity for distinguishing COvid-19 from other diseases associated with the same or similar clinical symptoms.
