Abstract

To evaluate the sensitivity of the intravoxel incoherent motion (IVIM) technique to changes in cerebral blood flow, we made measurements ofIVIM parameters in rat brain under conditions of altered arterial pCO(2). The arterial pCO(2) was varied over a range which would be expected to change cerebral blood flow from roughly 50 to 500 ml/(100 g.min). The IVIM measurements were made with suppression of extravascular water signal. The parameters f' (the apparent fraction of spins which have ''fast'' pseudodiffusion), D-1() (the ''fast-pseudodiffusion'' coefficient), and D-2() (the ''slow-pseudodiffusion'' coefficient) all showed statistically significant positive linear correlations with arterial pCO(2). These results suggest that the IVIM method, when used with suppression of extravascular water signal, is sensitive to changes in blood flow.
