Comet Tail Sign

2014
The sign has been originally described on chest radiographs. It is formed by distorted blood vessel(s) and a focal area of atelectatic lung adjacent to pleural thickening. The vessel(s) are seen as curvilinear soft tissue density or densities, extending from the medial margin of the atelectatic lung to the pulmonary hilum. When the vessels are multiple

"Comet tail" artefact in diagnosis of pulmonary congestion in patients with diastolic heart failure.

Georgian medical news, 2013
The aim of this study was to evaluate the importance of thoracic ultrasound examination in diagnosis of DHF. Total of 380 patients with HF were evaluated. 86 patients had diastolic HF (I group) and 294 patients had systolic HF (II group).

Early subclinical increase in pulmonary water content in athletes performing sustained heavy exercise at sea level: ultrasound lung comet-tail evidence.

American Journal of Physiology. Heart and Circulatory Physiology, 2011
Whether prolonged strenuous exercise performed by athletes at sea level can produce interstitial pulmonary edema is under debate. Chest sonography allows to estimate extravascular lung water, creating ultrasound lung comet-tail (ULC) artifacts.

"Ultrasound comet-tail images": a marker of pulmonary edema: a comparative study with wedge pressure and extravascular lung water.

Chest, 2005
BACKGROUND Echographic examination of the lung surface may reveal multiple "comet-tail images" originating from water-thickened interlobular septa. These images could be useful for noninvasive assessment of interstitial pulmonary edema.
