Abstract
Imaging plays an important role in the detection of coronavirus (COVID-19) pneumonia in both managing the disease and evaluating the complications. Imaging with chest computed tomography (CT) can also have a potential predictive and prognostic role in COVID-19 patient outcomes. The aim of this pictorial review is to describe the role of imaging with chest X-ray (CXR), lung ultrasound (LUS), and CT in the diagnosis and management of COVID-19 pneumonia, the current indications, the scores proposed for each modality, the advantages/limitations of each modality and their role in detecting complications, and the histopathological correlations.
Highlights
The coronavirus (COVID-19) pandemic, caused by a novel coronavirus named severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), continues to put stress on health care around the world and trouble the economy of a lot of countries
High-resolution chest computed tomography (CT) scans for COVID-19 patients should be performed with volumetric acquisitions in deep inspiration with a slice thickness
Khosravi et al [150] showed that baseline CT severity score (CT-SS) can predict adverse outcomes including days of recovery, intensive care units (ICUs) admission, and mortality; it appeared to be poorly correlated with initial disease severity
Summary
The coronavirus (COVID-19) pandemic, caused by a novel coronavirus named severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), continues to put stress on health care around the world and trouble the economy of a lot of countries. Chest imaging is currently indicated in COVID-19 patients with acute respiratory illness and in suspected cases to support rapid medical triage in the presence of high pretest probability for patients at high-moderate risk of progression [11,12]. Chest imaging has an important role in diagnostic support in the presence of typical imaging findings for COVID-19 and multiple negative RT-PCR results in the presence of high pretest probability [11,12,24]. In these selective cases, confirmation should be conducted with serology along with laboratory examinations [24]. First overview of the patients, especially in the emergency room; in hospitalized patients and in ICU
