Coronavirus CT Findings Linked to Disease Time Course

A new COVID-19 study out of Mount Sinai Health System in New York has just been published in the journal Radiology that looked at 121 patients from early to late-stage infection and linked CT findings to disease course

February 20, 2020 — In new research published today in the journal Radiology, researchers from Mount Sinai Health System in New York demonstrated that computed tomography (CT) findings in coronavirus disease 19 (COVID-19) cases are related to infection time course.

“Chest CT is a vital component in the diagnostic algorithm for patients with suspected COVID-19 infection. Indeed, given the limited number of rRT-PCR kits in some centers and the possibility of false negative rRT-PCR results, the National Health Commission of the People’s Republic of China has encouraged diagnosis based on clinical and chest CT findings alone,” the authors wrote.

The researchers analyzed chest CTs of 121 symptomatic patients infected with COVID-19 from four centers in China from January 18, 2020, to February 2, 2020, for common CT findings in relationship to the time between symptom onset and the initial CT scan.

They found ground-glass abnormality in early disease, followed by development of “crazy paving,” and finally increasing consolidation later in the disease course.

Recognizing imaging patterns based on infection time course is paramount for not only understanding the pathophysiology of infection, but also for helping to predict patient progression and potential complication development. 

“Future investigators may evaluate imaging findings in chronic patients.  Such work could evaluate if long-term complications potentially arise,” the authors wrote.
