Abstract: Xenon-enhanced CT imaging of cerebral blood flow is a method that has improved along with the technologies on which it is based. Today the technique provides more information at more brain levels with less xenon, and in a time frame that permits the information to be integrated into patient care. Quantitative blood flow studies that are accurate in patients with blood flow abnormalities and that enable the definition of the full range of flow values can identify regions of the brain most likely to benefit from efforts to improve blood flow. The ability to repeat studies within 20 minutes provides a powerful tool for studying normal and abnormal physiology.
