Synopsis

Non-invasive methods to evaluate voiding dysfunction in men are extremely limited. We report here a non-invasive, MRI-based protocol to characterize urethral biomechanics during voiding. All four subjects were able to void in the scanner with high-fidelity, 3D images of the urethra. These images were successfully analyzed for anatomy, function, and biomechanics. Future work will be aimed at furthering these methods and resulting metrics so that they may be applied clinically.
