ABSTRACT
Objective To evaluate usefulness of high-resolution MRI in quantitative analysis of femoral micro-structure.Methods This study included 110 cases which were divided into 4 groups according to the results of DXA.High-resolution MRI of left hip joint wasperformed on a 1.5T super-conductive MR scanner.3 ROIs were selected on the largest oblique-coronal images of femur to gain thebinary images derived from software processing and 30 parameters were analyzed.Results The parameters to be of statistical significance were 77% and 67%,respectively.Full points of structural parameters with significant difference were 6,4~6 points were 60% and 2~3 points were 40%.Trabecula connective parameters such as trabecula area,mean framework length and mean trabecula perimeter had positive correlation with bone density,r=0.547~0.722,0.58~0.654 and 0.573~0.688,P
