Susceptibility weighted imaging (SWI) is not only a valuable tool for brain imaging, but also for renal imaging. In this study, the sensitivity of SWI to kidney-function induced changes of blood flow is investigated. Because the blood oxygenation level dependent (BOLD) contrast of blood depends on the local blood flow, the SWI contrast has been investigated while the kidney function has been increased. SWI has been applied before and after water uptake. In healthy volunteers, the SWI contrast decreases after water uptake and then increases again to the equilibrium value of the resting state.
