摘要：近年来，肺部超声技术越来越受到人们的关注。肺部超声可以对肺组织以及胸膜进行快速的视觉评估，
用来诊断心源性肺水肿、急性呼吸窘迫综合征 (ARDS) 等肺部疾病。相较于 CT、磁共振成像 (MRI) 而言，超
声对人体无辐射危险，且超声技术简单、安全、成本相对较低。而肺超声伪影可以反映出诸多肺部组织病理信
息，临床诊断中能观察到的肺部伪影主要包括有 A 线、B 线与 Z 线。通过这些伪影可以对患者进行生理和病理
的诊断，尤其是 B 线具有非常重要的临床价值。该文就肺部超声伪影的产生机理、定量及半定量检测技术以及
肺超声伪影的临床应用进行综述。

Abstract: In recent years, more and more attention has been paid to pulmonary ultrasound technology. Pul-
monary ultrasound can provide rapid visual assessment of lung tissue and pleura to diagnose pulmonary diseases
such as cardiogenic pulmonary edema and acute respiratory distress syndrome (ARDS). Compared with CT
and magnetic resonance imaging (MRI), ultrasound has no radiation risk to human body, and it is portable,
safe and cheap. It is well known that pulmonary ultrasound artifacts can provide a lot of pathological infor-
mation of lung tissue. The pulmonary artifacts observed in clinical diagnosis mainly include A-line, B-line and
Z-line. These artifacts can be used for physiological and pathological diagnosis, especially the B-line has great
clinical value. In this paper, the mechanism of formation of pulmonary ultrasonic artifacts, quantitative and
semi-quantitative detection techniques and clinical application of pulmonary ultrasonic artifacts are reviewed.
Keywords: Pulmonary ultrasound artifact; B-line detection; Semi-quantitative detection; Application of
pulmonary ultrasound
