    Technegas, an ultra-fine dry aerosol with prolonged retention in the lungs, can be modified by altering the atmosphere in which the carbon particles are generated. The modified Technegas has much faster clearance from the lung. The half-time pulmonary clearances with modified Technegas were compared to those obtained with conventional 99mTc DTPA aerosol in 50 patients. Interstitial lung disease was suspected in 12 while 38 were infected with the human immunodeficiency virus and suspected of having opportunistic lung infection. In 22 nonsmokers in whom no evidence of active pulmonary pathology was demonstrable, the mean half-time with DTPA was 52.5 min whereas the mean half-time with modified aerosol was 10.1 min. The mean half-time in 14 smokers in whom there was also no evidence of active pulmonary disease was 28.3 min with DTPA and 7.0 min with the modified method. In the 14 patients in whom altered pulmonary permeability was demonstrated by a short DTPA half-time (mean 4.8 min) there was also an accelerated half-time with modified Technegas (mean 2.5 min). It is concluded that the modified Technegas procedure offers a simple but accurate method of identifying individuals having opportunistic infection or other diffuse lung pathology.
