| Outline of Final Research Achievements |
Significant differences were observed in spinal microarchitecture between control subjects and multiple myeloma patients without pathologic fractures. Independent predictors of multiple myeloma included TbTh and FD in male patients and DA in female patients. The prevalence of osteoporosis was significantly higher in post TACE patients than in control subjects. The cumulative radiation dose related to routine dynamic CT studies was a significant contributor to the prevalence of osteoporosis. The χ2 test for each parameter showed that male myeloma patients with a lower apparent trabecular width and FL had a greater prevalence of vertebral fracture than did patients without fracture. Also, the female patients with a lower vBMD, apparent bone volume/tissue volume, apparent trabecular number, fractal dimension, FL or stiffness, and greater Euler number or structure model index had a greater prevalence of vertebral fracture than patients without vertebral fracture.
