Cortical Bone Water Concentration: Dependence of MR Imaging Measures on Age and Pore Volume Fraction

摘要

The suppression ratio (the ratio of ultrashort echo-time MR imaging signal amplitude obtained without long-T2 suppression to that obtained with long-T2 suppression) can potentially be a better biomarker for cortical bone porosity than bulk bone water concentration, thereby providing quantitative insight into the structural degradation of cortical bone in degenerative bone disease.
