Plain language summary ○ This study assesses the effect of MRI field strength, age, and sex on renal perfusion and T1 measurements using pseudo-continuous arterial spin labeling (PCASL) and T1 mapping, noninvasive techniques for evaluating renal pathophysiology. ○ Sixteen healthy volunteers underwent same-day scans at 1.5 T and 3 T field strengths, repeated after 1 week. ○ Significant differences in T1, renal blood flow (RBF), and signal-to-noise ratios were found between field strengths.

Imaging myocardial perfusion under stress conditions is clinically useful for detecting potential areas of ischemia in patients with suspected coronary artery disease.1 A first-pass dynamic contrast-enhanced MRI technique that involves intravenous injection of a gadolinium-based contrast agent is commonly used to identify reduced perfusion by visual inspection of hypointense regions.2 Although this technique can also provide quantitative measurements of myocardial blood flow (MBF),...
