| 目的 采用超声断层成像(UT)比较青年人与老年人内侧腓肠肌和肱二头肌纹理特征。方法 前瞻性招募20名＜30岁(青年组)和22名≥60岁(老年组)健康成年人;采用环阵UT系统采集上、下肢图像,提取内侧腓肠肌和肱二头肌纹理特征并比较组间差异。结果 组间内侧腓肠肌灰度均值(GLM)、灰度方差(GLV)、对比度(CON)、同质性(HOM)、灰度熵(ENT)、灰度不均匀性(GLN)及游程长度不均匀性(RLN)差异均有统计学意义(P均＜0.05),肱二头肌GLM、GLV、CON、HOM及ENT差异均有统计学意义(P均＜0.05)。结论 青年人与老年人内侧腓肠肌和肱二头肌GLM、GLV、CON、HOM及ENT存在差异,即老年人肌肉发生结构重构和功能改变。 |

| Objective To compare the texture features of medial gastrocnemius and biceps brachii muscles between young and elderly individuals with ultrasound tomography (UT). Methods Twenty healthy adults under 30 years old (young group) and 22 healthy adults greater than or equal to 60 years old (elderly group) were prospectively recruited. A ring-array UT system was used to collect images of upper and lower limbs, the texture features of medial gastrocnemius and biceps brachii muscles were extracted and compared between 2 groups. Results Significant differences of gray level mean (GLM), gray level variance (GLV), contrast (CON), homogeneity (HOM), entropy (ENT), gray-level non-uniformity (GLN) and run-length non-uniformity (RLN) of medial gastrocnemius, as well as of GLM, GLV, CON, HOM and ENT of biceps brachii muscles were found between groups (all P＜0.05). Conclusion Significant differences of GLM, GLV, CON, HOM and ENT of medial gastrocnemius and biceps brachii muscles were found between young and elderly individuals, indicating that structural remodeling and functional changes in muscles happened in elderly individuals. |
