Lifesaving Sign in Non‐Contrast CT Scan in the Case of Pulmonary Thromboembolism

Abstract

ABSTRACT The two most important signs of pulmonary embolism (PE) in a non‐contrast CT scan include wedge‐shaped sub‐pleural opacity surrounded by an air‐space consolidation, along with a ground‐glass opacity in the center consistent with pulmonary infarction, also known as the reverse halo sign and the hyperdense lumen sign.
