Validation procedure through ultrasound-guided muscle biopsy (Hill and San-Millan, 2014). The ultrasound-guided muscle biopsy allows to determine the exact site from where the muscle biopsy was obtained. Only through this procedure is possible to correlate the glycogen content from the muscle biopsy with the echogenicity of the image corresponding to the muscle biopsy site.
