- Abstract
Pulmonary perfusion scintigraphy is a non-invasive, non-irradiating technique that provides functional information particularly useful both in diagnosis and in establishing the optimal therapeutic response for serious conditions such as bronchopulmonary carcinoma. In patients with bronchopulmonary cancer, pulmonary perfusion scintigraphy is used for the assessment of postoperative pulmonary function and of the maximum expiratory volume per second. The visualization of pulmonary perfusion is achieved by intravenous injection of radioactively labelled particles which are retained in the terminal pulmonary circulation, imitating the mechanism of the embolic accident; because of their dimensions, markedparticles are blocked at terminal pulmonary circulation without causing local haemodynamic changes. By computerized analysis of the number of impulses collected on images from anterior and posterior incidence, pulmonary function is determined, for each lung and in each and every pulmonary region. This quantitative analysis is useful in selecting patients for pneumonectomy and exclusion of those at high risk of postoperative respiratory failure. An estimated maximum expiratory volume per second less than 0.8 l or less than 40% is associated with an increased risk of morbidity and pulmonary post-intervention mortality and therefore excludes surgery.
