Abstract

Dynamic changes in T₂^* in the rat brain induced by the injection of Gd-DTPA are monitored using the U-FLARE sequence. Sensitivity to T₂^* is easily introduced into this sequence and may be freely varied. The images obtained display an adequate spatial resolution and contrast, for a temporal resolution of 1 s. Intensity-time curves and parametric images of regional cerebral blood flow (rCBV) are presented for three different blood pCO₂ values. The results presented clearly demonstrate that U-FLARE is a viable method for dynamically measuring changes in T₂^*, and thus has application in imaging of both perfusion and functional activation.
