Abstract

Pulmonary artery stenosis represents a group of disorders involving main, branch or peripheral pulmonary arteries with pain, dyspnea, hemoptysis or even no symptoms. Early diagnosis and timely intervention are crucial for reducing mortality, but timely diagnosis is challenging due to the non-specific symptoms. Computed tomography pulmonary angiography (CTPA) is useful in the diagnosis because it can provide more details about abnormal changes in the lumen, vessel wall and adjacent mediastinal structures. Congenital and acquired pulmonary artery anomalies have some characteristics on CTPA, which can be useful for differential diagnosis. Awareness of these conditions is important for radiologists. This pictorial review provides an overview of CTPA imaging features of pulmonary artery stenosis.

摘要

肺动脉狭窄是一组涉及主肺动脉、分支肺动脉或外周肺动脉的疾病，可伴有疼痛、呼吸困难、咯血，甚至无症状。早期诊断和及时干预对于降低死亡率至关重要，但由于症状不具特异性，及时诊断具有挑战性。计算机断层扫描肺动脉造影（CTPA）对诊断很有用，因为它可以提供有关管腔、血管壁和相邻纵隔结构异常变化的更多细节。先天性和后天性肺动脉异常在CTPA上有一些特征，有助于鉴别诊断。放射科医生了解这些情况很重要。本图文综述概述了肺动脉狭窄的CTPA成像特征。
