Xenon-133 postperfusion lung scintigraphy using 10% windows was compared with standard posterior preperfusion /sup 133/Xe ventilation scanning in 33 patients. The postperfusion /sup 133/Xe study identified all major defects and washout abnormalities. In five patients, the assessment of match or mismatch of defects was improved because of optimal positioning of the postperfusion ventilation study. Computer subtraction of background technetium-99m macroaggregated albumin activity improved detection of mild washout abnormalities in eight patients but did not change the diagnostic category in any case. Postperfusion ventilation scanning using 10% windows is an alternative to preperfusion ventilation scanning for major V/Q abnormalities.
