肺灌注联合CT肺动脉成像对肺动脉狭窄合并肺动脉高血压的诊断价值
Pulmonary perfusion imaging combined with computed tomography and pulmonary angiography in diagnosis of pulmonaryartery hypertension in patients with pulmonaryartery stenosis
摘要
Abstract
Objective To investigate into the value of pulmonary perfusion imaging combined with computed tomography and pulmonary angiography (CTPA) in diagnosis of pulmonary artery hypertension (PAH) in patients with pulmonary artery stenosis. Method Totally six patients diagnosed with PAH and pulmonary stenosis by right heart catheterization and pulmonary angiography, who underwent both99 mTc-MAA pulmonary perfusion imaging and CTPA examination, were analyzed. Results Pulmonary perfusion imaging combined with CTPA highly accorded with pulmonary angiography in detecting the pulmonary artery stenosis.The diagnostic accuracy in detecting the PAH of the two methods was 83％, and in a combined manner could reach 100％. Conclusion Pulmonary perfusion imaging could be used as a good testing tool for PAH with pulmonary artery stenosis and, combined with CTPA, can avoid unnecessary invasive test in some patients, thus having important clinical value.关键词
