Supersonic shear wave imaging was performed at rest with a linear transducer and a specialized\u2010preset procedure. The stability and validity of the shear waves were automatically assessed by the SSI procedure. The SSI images were visualized in a color\u2010coded elastographic image. In the postprocessing analysis, the ventral part of the urethral rhabdosphincter muscle was manually outlined. The mean V<jats:sub>s<\/jats:sub> and the mean E of the muscle were measured by the SSI procedure.
