[Estimation of lung water with 131I-antipyrine and 99mTc-HSA (author's transl)].
Extravascular lung water is estimated in vivo from indicator dilution curves of diffusible and non-diffusible tracers utilizing their different transit times as they pass the lung microvessels. 131I-antipyrine as the diffusible and 99mTc-HSA as the non-diffusible tracer were injected simultaneously, using a pneumatic injector. Indices for rELW/V and rELW/F were calculated using programs previously published, and gave numerical values for the presence and intensity of pulmonary interstitial oedema. Inaccuracies due to sequential inputs are avoided. 131I-antipyrine has a more convenient pulmonary interstitial oedema. Inaccuracies due to sequential inputs are avoided. 131I-antipyrine has a more convenient shelflife and can therefore serve for emergency and follow-up examinations. The results do not differ significantly form those with 123I-antipyrine, and the higher radiation burden is tolerable. A mobile set-up for bed-side measurements is described.
