Abstract
Pulmonary hypertension (PH) is defined as a pulmonary capillary wedge pressure >25 mm Hg. Patients tend to present with nonspecific symptoms centered on worsening dyspnea. The causes of PH are classified according to the Dana Point classification which groups causes of PH based on shared pathophysiology and treatments. In the initial work up of patients with PH, the goal of imaging is determine if there are findings of PH and to look for clues to the underlying cause so that patients are treated appropriately. MRI can be useful in the follow up of patients with PH, as it can evaluate for changes in the right ventricle.
肺动脉高压(Pulmonary hypertension, PH)定义为肺毛细血管楔压>25 mm Hg，患者往往表现为以呼吸困难加重为中心的非特异性症状。PH的原因根据达纳点分类分类，该分类基于共同的病理生理和治疗方法对PH的原因进行分组。在PH患者的初始工作中，影像学的目标是确定是否有PH的发现，并寻找潜在原因的线索，以便患者得到适当的治疗。MRI在PH患者的随访中很有用，因为它可以评估右心室的变化。
