Whole body muscle and bone segmentation on MRI
MuscleMap MRI segments 99 muscles and bones from the neck to the lower legs, including the trapezius, erector spinae, psoas major, vastus lateralis, gastrocnemius, femur, and tibia, with left and right kept apart. Scans of different MRI contrasts go through the same AI task. Researchers use this whole-body muscle segmentation on MRI to compare individual muscles between groups and measure muscle volume before and after an exercise or diet program.
Find answers to research questions like: Which muscles lose the most volume with age? How does muscle volume change over months in the same people? Is muscle size related to strength?
