In this study we focus on exploring the use of a single sided low-field MR systems to continuously measure perfusion. For this purpose we developed a contrast-free measurement technique - tentatively named Inhomogeneous Flow-sensitive Alternating Inversion Recovery (IFAIR). This new technique, adapted from the FAIR ASL protocol, was designed to be suitable for inhomogeneous field conditions and to function without pulsed gradient fields. The IFAIR signal response displayed a consistent proportional relationship to flow velocity, with potential to allow for quantitative flow-dependent measurements.
