  • Title: [Three-stage method in lung scintigraphy: ventilation, diffusion and perfusion (author's transl)].
    Author: Erbs G, Doll J, Johannsen J, Kleinhans S.
    Journal: Rofo; 1975 Jul; 123(1):13-8. PubMed ID: 130291.
    Abstract:
    A combination of three stages--ventilation, "perfusion" and diffusion-- has proved to be the optimal method in the scientigraphic exmaination of the lung. 85mCrypton is preferred for ventilation studies compared with 133Xenon, in view of its more suitable radiation energy and lower solubility. In the pre and post-operative investigation of the lungs, ventilation estimations are essential, providing a more reliable perameter than "perfusion estimations". The results from "perfusion" measurements with MAA or microspheres frequently do not correspond with those obtained by 133Xenon. It is still debatable whether the use of MAA or microspheres provide perfusion values and it would be better at present to speak of MAA fixation results.
