Abstract
The invention discloses diagnostic compositions for use in obtaining images of a patient's lungs. The basic components of the composition of the invention are sodium pertechnetate which is radioactive and ethanol. This composition may be combusted and the resulting products cooled or alternatively the composition may be inserted into a pressure vessel with an aerosol. In both cases a gas like mixture results. A particular advantage is that a patient is able to breath the mixture of the invention in a normal way and does not need to undergo any training in inhalation.
