Early Detection of Osteoporosis in Space (EDOS)
Principal Investigator
Research Area:
Skeletal physiology
Species Studied
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.
