HealthDay News – Chest computed tomography (CT) has a low level of misdiagnosis of the novel coronavirus (COVID-19), according to a study published online March 4 in the American Journal of Roentgenology.

Yan Li, Ph.D., and Liming Xia, MD, both from Huazhong University of Science and Technology in Wuhan, China, reviewed clinical information, CT images, and related image reports from the first 51 patients diagnosed with COVID-19 infections Nucleic acid tests confirmed (23 women and 28 men; age group 26 to 83 years) and two patients with adenovirus (one woman and one man; ages 58 and 66 years).

The researchers report that COVID-19 was misdiagnosed as a common infection in the first CT study of two inpatients with underlying disease and COVID-19. In the first CT study, the remaining 49 patients with COVID-19 and two patients with adenovirus were correctly diagnosed with viral pneumonia. General CT characteristics of COVID-19 included mat opacities and consolidations with or without vasodilatation, interlobular septal thickening, and air bronchogram signs. Unusual CT features included the “inverted halo” sign and lung nodules with a halo sign. The researchers found an overlap between CT findings of COVID-19 and CT findings of adenovirus infection.

“We found that chest CT had a low rate of missing COVID-19 diagnoses (3.9 percent; two out of 51) and, as a standard method for rapidly diagnosing COVID-19, can be useful to optimize patient management.” the authors write.
