Radionuclidic lung-imaging procedures in the assessment of injury due to ammonia inhalation.

Clinical, physiologic, and bronchoscopic findings in a young man with acute injury of the respiratory tract due to inhalation of ammonia are described. Six months later, the patient's pulmonary function was reassessed by three radionuclidic lung-imaging procedures, which first revealed the sites and extent of the persisting obstructive disease processes. The diagnostic accuracy of the initial findings with radioactive xenon and aerosol were verified by the results of repeated bronchoscopic examination, bronchographic studies, standard pulmonary function tests, and lung-imaging procedures.

Imaging small pulmonary ischemic lesions after radioactive carbon monoxide inhalation.

A new method is described for imaging small ischemic regions in the lung immediately after a single breath of radioactive carbon monoxide (11CO). A tungsten-collimated scintillation camera is used to visualize the 0.51-MeV annihilation photons due to the 11C. In normal dogs the entire field is cleared of 11CO within 10 sec. However, in dogs with experimentally occluded 2-mm-diam segmental arteries, the ischemic but well-ventilated segment appears as a region of persistent high radioactivity, due most likely to temporary entrapment of 11CO-labeled red blood cells in the ischemic region. This technique also provides a simple noninvasive means for instantly labeling the systemic circulation without left heart catheterization.
