A case of pulmonary vein stenosis as a result of prior atrial fibrillation focus procedures for atrial fibrillation, correlated with magnetic resonance (MR) pulmonary angiography, is presented. Restricted flow to the right lung in similar quantities measured by nuclear medicine and MR techniques is observed, with perfusion scintigraphy demonstrating decreased but not absent flow to the right lung and left lower lobe and with MRI demonstrating restriction of flow through the right and left lower pulmonary veins. The sharp differences in venous outflow can be seen by MR, whereas their effects are visible by scintigraphy.
现介绍 1 例因心房颤动而进行的房颤病灶处理导致的肺静脉狭窄病例，该病例与磁共振（MR）肺动脉造影相关。观察到右肺的血流受限，其数量与核医学和 MR 技术相似，灌注闪烁显像显示右肺和左下叶的血流减少但未完全消失，而 MRI 显示右肺和左下肺静脉血流受限。MR 可观察到静脉流出的明显差异，而闪烁显像可观察到其影响。
