| 520 | 3 | |a Osteoporosis is a disease of poor bone quality. Bone mineral density (BMD) has limited ability to discriminate between subjects without and with poor bone quality, and assessment of bone microarchitecture may have added value in this regard. Our goals were to use 7T MRI to: (1) quantify and compare distal femur bone microarchitecture in women without and with poor bone quality (defined clinically by presence of fragility fractures); and (2) determine whether microarchitectural parameters could be used to discriminate between these two groups. This study had institutional review board approval, and we obtained written informed consent from all subjects. We used a 28-channel knee coil to image the distal femur of 31 subjects with fragility fractures and 25 controls without fracture on a 7T MRI scanner using a 3-D fast low angle shot sequence (0.234mm×0.234mm×1mm, parallel imaging factor=2, acquisition time=7min 9s). We applied digital topological analysis to quantify parameters of bone microarchitecture. All subjects also underwent standard clinical BMD assessment in the hip and spine. Compared to controls, fracture cases demonstrated lower bone volume fraction and markers of trabecular number, plate-like structure, and plate-to-rod ratio, and higher markers of trabecular isolation, rod disruption, and network resorption (p<0.05 for all). There were no differences in hip or spine BMD T-scores between groups (p>0.05). In receiver-operating-characteristics analyses, microarchitectural parameters could discriminate cases and controls (AUC=0.66-0.73, p<0.05). Hip and spine BMD T-scores could not discriminate cases and controls (AUC=0.58-0.64, p≥0.08). We conclude that 7T MRI can detect bone microarchitectural deterioration in women with fragility fractures who do not differ by BMD. Microarchitectural parameters might some day be used as an additional tool to detect patients with poor bone quality who cannot be detected by dual-energy X-ray absorptiometry (DXA). | |
