title: Gallium-67 citrate scintigraphy in pulmonary embolism.
abstract: Eight cases of pulmonary embolism were evaluated with Ga-67 citrate scintigraphy. Of the eight patients, all but one showed evidence of abnormal Ga-67 citrate localization within involved regions of the lung as demonstrated by ventilation-perfusion lung scintigraphy. The sole patient who did not demonstrate Ga-67 localization within the lung had marked breast accumulation of the radiotracer which may have obscured lung parenchymal uptake. Since Ga-67 citrate is known to accumulate within inflammatory lung processes, this radiotracer would not have a specific role in differentiating pulmonary embolism from these conditions. This study disagrees with the results of other studies in the medical literature that describe such a role.
