Rapid, spectrally resolved imaging of 129Xe in the rat brain may allow for measurement of cerebral blood flow, as well as tissue characteristics such as relaxation rates and partition coefficient which may be useful for characterizing neurological disease or injury such as stroke. In this work, the feasibility of spiral-IDEAL for spectrally resolved 129Xe in the rat brain was demonstrated during steady state ventilation of a rat. With future improvements to the signal-to-noise ratio, it is proposed that spiral-IDEAL will allow for rapid, spectrally resolved imaging of the brain.
