Sollmann N, Franz D, Burian E, et al. - This study was intended to evaluate paraspinal muscle characteristics and lumbar bone mineral density (BMD) and their relationships in routine abdominal multi-detector CT (MDCT) as well as the impact of osteoporotic vertebral fractures on such associations. This study enrolled a total of 116 individuals (69.7 ± 8.1 years, 72 males) who underwent routine abdominal MDCT (oncological staging and/or follow-up for tumor recurrence) and these individuals were assigned to a fracture and control group (age- and gender-matched), depending on the presence or absence of lumbar osteoporotic vertebral fractures. The routine abdominal MDCT without dedicated software can assess paraspinal muscle characteristics and lumbar BMD seamlessly. They found level-dependent synergies between paraspinal muscle characteristics as well as lumbar BMD. It was noted that vertebral fracture status was independent of paraspinal muscle characteristics.
