引起肺动脉高压(PAH)的原因多样,包括多种先天性和获得性心脏病,以及原发于肺血管、肺、胸膜和胸壁的疾病。CT评价PAH传统的任务包括对肺血管和肺实质的评估,但对心脏的评估有限。多层CT的技术进步,提高了影像的时间和空间分辨力,可精确地显示心脏的形态。CT肺动脉成像(CTPA)广泛应用于 Pulmonary hypertension (PAH) is caused by a variety of causes, including a wide range of congenital and acquired heart diseases, as well as diseases that originate in the pulmonary vessels, lungs, pleura, and chest wall. The traditional tasks of CT assessment of PAH include assessment of pulmonary blood vessels and lung parenchyma, but limited assessment of the heart. Multi-layer CT technology advances, improve the image of time and space resolution, can accurately display the shape of the heart. CT pulmonary angiography (CTPA) is widely used
