Quantitative measurement of renal arterial spin labeling: a noninvasive indicator of perfusion in renal artery stenosis
Motivation: There are few validated noninvasive indicators for renal perfusion and renal function in patients with renal artery stenosis (RAS)Goal(s): To explore the utility of arterial spin labeling (ASL) as a noninvasive indicator of renal perfusion and function in patients with RAS. Approach: We evaluated correlations between ASL-measured preoperative renal blood flow (RBF) and renal function, then compared preoperative and postoperative RBF. Results: ASL-measured RBF was significantly correlated with renal function. ASL was able to evaluate perfusion improvement in patients with RAS after interventional therapy. Impact: ASL can be used as an indicator of renal function and perfusion in patients with RAS. It can also be used to assess changes in renal perfusion after interventional therapy.
