Chest X-rays of macaques exposed to nebulized or bronchoscopically administered perflubron. Representative posteroanterior (PA; A and C) and lateral (B and D) chest X-rays from two macaques, taken immediately after 1 hr of nebulized perflubron inhalation, demonstrate random pooling of inhaled perflubron in dependent lung regions and also swallowing of nebulized perflubron that had condensed in the oropharyngeal cavity (red arrows).
