An example of discordant findings of thromboembolic disease between ventilation–perfusion scanning and computed tomography with angiography of a single patient. (A) Ventilation examination with Xe-133 in right posterior oblique view showing no ventilatory defects. (B) Perfusion image obtained after injection of Tc-99m macroaggregated albumin in right posterior oblique view showing perfusion defects in the right upper lobe, right middle lobe, and right lower lobe (blue arrows). There is an area of increased intensity in the superior segment of the right lower lobe that represents artifact from insignificant clotting of the Tc-99m macroaggregated albumin (white asterisk). (C) Computed tomographic pulmonary angiogram in coronal view showing tortuous and dilated pulmonary arteries but no perfusion defects or other signs of chronic thromboembolic disease within the pulmonary arteries. (D) Computed tomographic pulmonary angiogram in axial view showing the proximal pulmonary arteries with a dilated main pulmonary artery but no perfusion defects or signs of chronic thromboembolic disease. (E) Pulmonary angiogram with truncated left upper lobe segmental pulmonary artery (blue arrow). (F) Pulmonary angiogram with truncated and pruned right middle lobe segmental pulmonary artery (blue arrow) and wedge-shaped area of hypoperfusion.
