چکیده انگلیسی
This study explored the efficacy of shear wave ultrasound elastography (SWUE) for quantitative evaluation of denervated muscle atrophy in a rabbit model. The elastic modulus of the triceps surae muscle was measured with SWUE and compared with histopathologic parameters at baseline and at various post-denervation times (2, 4 and 8âwk) with 10 animals in each group. Our results revealed that the elastic modulus of denervated muscle was significantly lower at 2âwk but higher at 8âwk compared with that at the baseline (pâ<0.05), and no significant difference was found between the elastic modulus at 4âwk and that at the baseline (pâ>â0.05). The wet-weight ratio and the muscle fiber cross-sectional area of the denervated muscle decreased gradually during the 8âwk post-denervation together with a gradual increase of the collagen fiber area (pâ<0.05). In conclusion, SWUE was useful for quantitative evaluation of muscle denervation. The decreased elastic modulus might be an early sign of denervated muscle atrophy.
