lüll Blood oxygen level-dependent MR imaging of the kidneys Li LP; Halter S; Prasad PVMagn Reson Imaging Clin N Am 2008[Nov]; 16 (4): 613-25, viiiOxygenation status plays a major role in renal physiology and pathophysiology, and thus has attracted considerable attention in recent years. While much of the early work and a significant amount of present work is based on invasive methods or ex vivo analysis, and is therefore restricted to animal models, blood oxygen level-dependent (BOLD) MR imaging has been shown to extend these findings to human beings. BOLD MR imaging is most useful in monitoring effects of physiologic or pharmacologic maneuvers. Several teams around the world have demonstrated reproducible data and have illustrated several useful applications. Studies supporting the use of renal BOLD MR imaging in characterizing disease with prognostic value have also been reported. This article provides an overview of current state-of-the art of renal BOLD MR imaging.|Humans[MESH]|Kidney/*physiology[MESH]|Magnetic Resonance Imaging/*methods[MESH]|Oxygen/*blood[MESH] |
