Abstract:
This study evaluated the real-world diagnostic performance of Radiological Society of North America COVID-19 consensus reporting guidelines among 2618 chest CT reports from the author's health care network from April 2020 through March 2021; reverse-transcriptase polymerase chain reaction served as the reference. Typical findings exhibited sensitivity of 68% and specificity of 91%, similar to performance reported in research settings. PPV of 52% was lower than previously reported, attributed to low COVID-19 prevalence. Accuracy improved from 84% in April 2020 to 92% in March 2021 (p = .03).

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
