Abstract

Objective To investigate the role of 99Tcm-macroaggregated albumin (99Tcm-MAA)pulmonary perfusion imaging in evaluating thrombolytic therapy in pulmonary embolism. Methods Date of 54 patients with acut pulmonary embolism diagnosed by 99Tcm-MAA pulmonary perfusion imaging combined with radiography were analyzed retrospectively. Among them, pulmonary perfusion imaging was also performed one week after thrombolytic therapy. In some cases, pulmonary perfusion imaging was performed three months after thrombolytic therapy. Results The results of radiography were normal in all cases, among 347 abnormal pulmonary segments in 54 cases. 164 (47.3%) and 199 (57.4%) segments were restored to normal 1 week and 3 months later(χ2=10.68, P<0.05). Conclusion As a non-invasive diagnostic method,99Tcm-MAA pulmonary perfusion imaging play an important role in evaluating the therapeutic effectiveness of thrombolytic therapy in patients with pulmonary embolism. Key words: Pulmonary embolism; Technetium Tc 99m aggregated albumin; Radiography,thoracic; Embolization, therapeutic
