在这项研究中,基于质子密度脂肪分数(PDFF)图的纹理分析,研究了颈椎和腰椎椎旁肌肉组织的关联,以识别性别和解剖位置特定的结构模式。 79 名志愿者(25 名男性,54 名女性)参与了本研究(平均年龄±标准差:男性:43.7±24.6 岁;女性:37.1±14.0 岁)。使用 PDFF 图的手动分割,执行纹理分析并提取纹理特征。在竖脊肌中观察到男性和女性之间平均 PDFF 存在显着差异 (p < 0.0001),而在颈部肌肉组织和腰肌中平均 PDFF 没有显着差异 (p > 0.05)。其中,在所有包含的肌肉群中,男性的方差(全局)和峰度(全局)值均显着高于女性(p < 0.001)。不仅平均 PDFF 值 (p < 0.001),而且三个肌肉区之间的方差(全局)(p < 0.001)、能量 (p < 0.001)、熵 (p = 0.01)、均匀性 (p < 0.001) 和相关性 (p = 0.037) 也存在显着差异。颈椎和腰椎椎旁肌肉组织的组成似乎具有性别特异性,并且具有解剖位置特异性的结构模式。
In this study, the associations of cervical and lumbar paraspinal musculature based on a texture analysis of proton density fat fraction (PDFF) maps were investigated to identify gender- and anatomical location-specific structural patterns. Seventy-nine volunteers (25 men, 54 women) participated in the present study (mean age ± standard deviation: men: 43.7 ± 24.6 years; women: 37.1 ± 14.0 years). Using manual segmentations of the PDFF maps, texture analysis was performed and texture features were extracted. A significant difference in the mean PDFF between men and women was observed in the erector spinae muscle (p < 0.0001), whereas the mean PDFF did not significantly differ in the cervical musculature and the psoas muscle (p > 0.05 each). Among others, Variance(global) and Kurtosis(global) showed significantly higher values in men than in women in all included muscle groups (p < 0.001). Not only the mean PDFF values (p < 0.001) but also Variance(global) (p < 0.001), Energy (p < 0.001), Entropy (p = 0.01), Homogeneity (p < 0.001), and Correlation (p = 0.037) differed significantly between the three muscle compartments. The cervical and lumbar paraspinal musculature composition seems to be gender-specific and has anatomical location-specific structural patterns.
