Abstract：
:The ability to differentiate between well-oxygenated and poorly-oxygenated tumors may play an important role in selecting an optimal therapeutic regime for tumor treatment of the individual patient. We present preliminary results in the development of a dynamic functional MRI method for mapping tissue oxygenation and blood flow distribution in humans simultaneously. We applied interleaved Blood Oxygenation Level Dependent (BOLD) and Flow-sensitive Alternating Inversion Recovery (FAIR) sequences to detect signals as a subject is inspiring gases of varying oxygen concentration. The method allows quantitation of the spatial distribution and time course of the important physiological functions that are easily registered with high resolution anatomic MR images. It may be used to critically evaluate the efficacy of varying durations of carbogen breathing in tumor patients, and allow a quantitative evaluation of the roles of carbogen and other radiosensitizers as potential adjuncts to radiotherapy and drug therapies.
