| Popis: | Muscle volume is an essential parameter in clinical evaluation and in biomechanical model development. Nevertheless, the difficulty in volumic muscle reconstruction from medical images is the noise they contain that limits the efficiency of image processing to automatically segment muscle. This study was conducted to explore hip muscle volume from CT-scan acquisition and to analyze the variability of muscle volume for a population of 98 subjects with age ranged from 21 to 94 years. To obtain three-dimensional muscle reconstruction, a method based on a deformation of a parametric specific object generated from a reduced number of muscle contours was used. A reproducibility study was conducted for muscle volume estimation. Coefficient of variation was found less than 8.9% and intraclass correlation coefficients were greater than 0.88. Results showed no significant difference between left and right muscles for this population. After adjustment to age and body mass index, hip muscle volumes were significantly different between men and women. This muscle volume reconstruction method allowed quantifying muscle volume distribution within a large population. |
