Several non-invasive methods are available to measure bone density in different regions of the skeleton. Bedrest and microgravity both lead to bone loss, which is more marked in the lower parts of the skeleton. The bone loss can be monitored by non-invasive techniques in longitudinal studies when precision (i.e.

The Medical letter on drugs and therapeutics, 1996
Recently, several methods for measurement of bone density have been developed. Among them, dual X-ray absorptiometry (DXA) is now considered to be a standard method in bone densitometry. In most cases, values by DXA measurement reflect bone strength and thus measurements of lumbar spine and femoral neck by DXA are used for diagnosis of osteopenia or ...

Ultrasonic Pulmonary Densitometry
Investigative Radiology, 1975The feasibility of using A-mode ultrasound to measure lung density changes was tested in two studies. (A) Wet sponges were used as experimental analogs of the lung. The sponges were weighed. A-mode recordings were obtained by placing the transducer face against a sheet of film in contact with each sponge.
