Pulmonary venous stenosis on ventilation-perfusion scintigraphy: a correlation with dynamic magnetic resonance pulmonary angiography.
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.
