MR oximetry based on quantitative T2 measurement is a noninvasive technique for measuring blood oxygen saturation. In this study, we apply an improved technique, Magnetic resonance Oximetry with Velocity Encoding, in vivo. This technique uses Fourier velocity encoding to isolate moving blood from static tissue based on velocity.
