UCSF/Baylor team uses new method to measure bone loss in astronauts flying long mission
...measurements of the heel bone (measured by DXA and ultrasound technology) as indicators for how much central skeletal bone astronauts are losing in space. The heel is an appealing measurement site because it is easily accessible, explained Lang.
