Radionuclide study in pulmonary sequestration.
A radionuclide hemodynamic study was helpful in demonstrating blood supply from the aberrant artery in pulmonary sequestration. Two regions of interest were set up in corresponding lower lung fields of a patient suspected of sequestration in the left lower lobe. Following i.v. injection of Tc-99m albumin, radioactively appeared in the the left target area 8-10 sec behind that on the right. This delay is due to the systemic arterial supply to the sequestration, rather than through the pulmonary artery.
