Pulmonary scanning: quantitative evaluation of pulmonary arterial flow

Journal Article:

Abstract

From ten normal subjects of both sexes, the quantitative regional blood flow of the pulmonary artery was evaluated using scanning with macroaggregated radio-iodinated (/sup 131/I) albumin. It was possible to conclude that: the digital recording of data (counts/cm/sup 2/), from any particular area of interest, is the best method for this evaluation; the lung, even being a thick organ, can be well studied by quantitative scanning, since its structure doesn't hinder the passage of radiations because it is covered only by the thoracic wall; scanning can be used to evaluate regional perfusion of the pulmonary artery, based on the proportionality between density of aggregates and blood flux in the different areas; the concentration of macroaggregates on the lung's superior section never reaches more than 40% of the radioactivity of the whole lung; there is no significant difference between left and right lungs, concerning the relationship between radioactivity on the superior section and the total area and quantitative analysis of pulmonary artery flow by means of scanning is a possible, reliable, and safe technique, without distress for the patient.
