The correlation between the acute, invasive diffusible [ u C]iodoantipyrine technique for cerebral blood flow and the noninvasive xenon-enhanced computed tomographic method has been assessed by simultaneous measurements in the baboon. Blood flows in small tissue volumes (about 0.125 cm 3 ) were directly compared in normal and low flow states. These studies demonstrate a statistically significant association between the two methods (/?< 0.001). Similar correlations were obtained by both the
