title: [An evaluation of inhalation and perfusion scintigraphy with 81mKr (author's transl)].
abstract: As 81mKr is a radioactive noble gas which has a very short half-life of 13 seconds, it leads no environmental contamination in a laboratory room. Because of its low radiation dose in the human body, it had many merits in routine tests of the inhalation and perfusion scintigraphy, which were very useful extremely in infants, old men and severe patients in need of cooperation. The studies with 81mKr were, either, useful as a load test, since these could repeatedly readily, evaluate the ventilation and perfusion dynamics before and after administration of drugs and show the distribution of the ventilation and perfusion correspond to the various lung volume level.
