This study was performed to assess the relationship of
3T-MR- and MDCT-derived trabecular bone measurements
with micro-CT measures as the gold-standard. L2 and L3
vertebral bodies of fresh human cadaver vertebrae were
scanned. The under- and overestimation of parameters may
be related to low spatial resolutions and susceptibility
artifact. The MRI/MDCT-derived measurements correlated
moderately with the gold-standards with the exception of
Tb.Th. 3T MRI- and MDCT derived measures show
significant correlations with micro-CT-derived
parameters, suggesting that the two methodologies assess
similar and complementary characteristics of bone.
