Blood flow in canine tibial diaphysis estimated by iodoantipyrine- 125 I washout.

Comparison of [I]HIPDm and [I]Iodoantipyrine in Quantifying Regional Cerebral Blood Flow in Rats

We determined regional cerebral blood flow (rCBF) using [I]HIPDm [ iV'-(2-hydroxy-3-methyl-5-iodobenzyl)-l,3-propanediamine] and [I]iodoantipyrine autoradiography under control and pathologic conditions (hypercapnia [acidosis], hypocapnia [alkalosis], and disrupted blood-brain barrier) conditions in 35 rats. In control rats, HIPDm rCBF (indicator fractionation method, n = 5) was lower than the ...

Estimation of coronary blood flow by washout of diffusible indicators.

Intrarenal distribution of blood flow in rats determined by 125I-iodoantipyrine uptake.

Regional Cerebral Blood Flow Estimated by Xenon Inhalation

Regional Cerebral Blood Flow Estimated by TMXenon Inhalation • A method is described for estimating the clearance rate and fractional blood flow of the fast (gray matter) compartment of the brain from the first ten minutes of Xe clearance curves, following a one-minute inhalation. Computer-simulated data were used to test the adequacy of the two-compartmental model employed, and to evaluate the...

Regional cerebral blood flow estimated by 133-xenon inhalation.

A method is described for estimating the clearance rate and fractional blood flow of the fast (gray matter) compartment of the brain from the first ten minutes of 122 XE clearance curves, following a one-minute inhalation. Computer-simulated data were used to test the adequacy of the two-compartmental model employed, and to evaluate the stability of the parameters in the presence of random nois...
