Abstract
The relative sensitivities of 81mKr and 127Xe in detecting lung ventilation defects was evaluated in 80 patients with nonembolic pulmonary diseases. 81mKr ventilation images (500,000 count) were interdigitated with 99mTc-macroaggregated albumin perfusion images; both were compared with 127Xe images. The distributions of the 2 gases were compared on the basis of point-by-point computer analyses, 127Xe was more sensitive than 81mKr in clinical evaluations of scintiphotos, although they were equivalent by computer analyses, in indicating regions of impaired ventilation in patients with obstructive airways disease.This publication has 14 references indexed in Scilit:
