Muscle volumetry from low-field scans and its relation to performance in physical activities

Here we show the results of the first systematic study performed in our low-field 72 mT MRI scanner. Calf images were acquired from 35 volunteers whose performance was measured during different physical activities before the scan. We segmented the images to determine the cross-sectional area and volume of the gastrocnemius muscles and correlated the results with the muscular activity measurements of the volunteers. We found that the medial gastrocnemius muscle volume correlates significantly with participants weight and unilateral jump capacity.
