Influence of statistical noise on the determination of the single kidney 99Tcm-DTPA clearance.

abstract：:The alveolar permeability (AP) in 21 patients with active diffuse infiltrative lung disease (ILD) was measured by 99Tcm-diethylenetriaminapentaacetate (DTPA) radioaerosol inhalation lung scintigraphy. The degree of AP damage in ILD was presented as the slope (% min-1) of the time-activity curve from the dynamic lung i...
