title: Quantitation of pulmonary gallium-67 uptake: comparison of computer-derived indices.
abstract: A variety of computer-derived indices of pulmonary gallium-67 were compared in 51 subjects with and without interstitial lung disorders. An index which quantitates lung uptake in relation to liver uptake, both being corrected for tissue background activity over the thigh, was the most reliable in differentiating between the two patient groups. The index is easily derived using standard computer techniques, so permitting further studies to assess its role in serial assessments of the progress of these disorders.
