    A Laib
    Institute for Biomedical Engineering, University of Zurich and Swiss Federal Institute of Technology ETH
    Technol Health Care 6:329-37. 1998
    ..We conclude that even in a homogenous group such as postmenopausal women, there are considerable differences in the reason why bone is weakened and that high resolution 3D-QCT allows to differentiate between various types of bone loss...

    A Laib
    Institute for Biomedical Engineering, University of Zurich, Switzerland
    Med Biol Eng Comput 38:326-32. 2000
