title: Postperfusion ventilation studies in the diagnosis of pulmonary embolism. An economic appraisal.
abstract: Postperfusion lung ventilation imaging with xenon-127 (Xe-127) gas was evaluated from an economic perspective. Results of five years experience at a tertiary referral center suggest that the use of postperfusion lung ventilation techniques can significantly reduce patient costs for diagnostic studies and may reduce institutional costs for radiopharmaceuticals.
