Identifying PAH is a challenge for clinicians, in part due to its nonspecific symptoms, such as dyspnea, chest pain, heart failure, and palpitations. As a result, the accurate diagnosis of PAH is often delayed up to 2 years after symptom onset. This article describes the role of new imaging technology in improving the diagnosis and assessment of patients with PAH.</style></abstract><number><style face="normal" font="default" size="100%">7</style></number><volume><style face="normal" font="default" size="100%">10</style></volume></record></records></xml>
