“…For example, one study published in the American Journal of Roentgenology on February 20, 2020 found that there was a low miss rate for COVID-19 on chest CT (3.9% 2/51 cases). Therefore, a negative chest CT may assist in management by allowing physicians to determine whether quarantine is warranted when the patient is within the incubation window [4] . However, in mid-March of 2020, the ACR issued an official statement on this topic and acknowledged that under current shortages and delays in testing: "some medical practices are requesting chest CT to inform decisions on whether to test a patient for COVID-19, admit a patient or provide other treatment.…”

a b s t r a c tThe SARS-CoV-2 infection , originally reported in Wuhan, China, has rapidly proliferated throughout several continents and the first case in the United States was reported on January 19, 2020. According to the ACR guidelines issued shortly after this disease was declared a pandemic, radiologists are expected to familiarize themselves with the CT appearance of COVID-19 infection in order to be able to identify specific findings of this entity.This case report discusses the relevant imaging findings of one of the first cases in the midwestern United States. It involves a 60-year-old man who presented with fever, dyspnea, and cough for 1 week and subsequently tested positive for COVID-19. The utility of the noncontrast CT chest in the diagnosis of COVID-19 has been controversial, but there are specific imaging findings that have been increasingly associated with this virus in the appropriate clinical context. The stages of imaging findings in COVID-19 are considered along with the implications of fibrosis throughout the stages. Future considerations include using artificial intelligence algorithms to distinguish between community acquired pneumonias and COVID-19 infection.

“…Pulmonary vascular enlargement (PVE), also known as pulmonary vascular widening, is defined as the widening of the subsegmental pulmonary vessel (pulmonary arteries and veins) with a diameter of more than 3 mm around and/or inside the opacity on CT (Figures 4a and 4b) [24,25,27,32,35,39]. Although the pathophysiology of PVE is not fully understood, PVE plays a potential diagnostic role for COVID-19.…”

A new type of coronavirus (2019-nCoV) is rapidly spreading worldwide and causes pneumonia, respiratory distress, thromboembolic events, and death. Chest computed tomography (CT) plays an essential role in the diagnosis of viral pneumonia, monitoring disease progression, determination of disease severity, and evaluating therapeutic efficacy. Chest CT can show important clues of 2019-nCoV disease (also known as COVID-19) in patients with an appropriate clinic. Prompt diagnosis of COVID-19 is essential to prevent disease transmission and provides close clinical observation of patients with clinically severe disease. Therefore, radiologists and clinicians should be familiar with the CT imaging findings of COVID-19 pneumonia. Herein, we aimed to review the imaging findings of COVID-19 pneumonia and examine the critical points to be considered for imaging in cases with COVID-19 suspicion.

“…Two days after admission (B), the size, density, and distribution of these opacities had progressed (arrows) tachypnea, she did not develop significant hypoxemia. After admission, a computed tomography (CT) scan ( Figure A) revealed the typical COVID-19 findings of patchy peripheral and subpleural ground-glass opacities 4 in the left lower lobe/lingula junction. The right middle lobe of the lung also showed a small subpleural opacity of uneven density and blurred margins.…”
