Early Detection of Osteoporosis in Space (EDOS)
Bone and calcium physiology
Scientific Name: Homo sapiens Species: Human
The objective of Early Detection of Osteoporosis in Space (EDOS) is to detect bone micro-architectural changes and to provide a better evaluation of the kinetics of bone loss recovery postflight. Measurements will include XtremeCT, Dual-energy X-ray absorptiometry (DEXA) and analysis of bone markers (blood samples). XtremeCT is a three-dimensional peripheral quantitative computed tomography (3DpQCT) technique developed by SCANCO Medical located in Switzerland.

Pre- and postflight densitometry and bone architecture measurements will be collected by this Computed Tomography device with the goal to evaluate the bone modifications process and evolution at a micro-architectural level on astronauts’ and cosmonauts’ tibia and radius and in the frame of space missions. Blood samples will be collected in order to match their results with the ones obtained from the bone densitometry and architecture measurements.
This experiment is in progress.
