Quantitative assessment of zonal trabecular volumetric bone mineral density in middle-aged and elderly women using quantitative computed tomography.

ABSTRACT:

Background

To explore the feasibility of the 9 zonal trabecular volumetric bone mineral density (trabecular vBMD) method in the first lumbar vertebral body (L1) and to assess the zonal trabecular vBMD distribution of L1 in women aged 50-80 years.

Methods

A total of 578 women patients underwent a quantitative computed tomography (CT) scan of the L1 vertebra, and these patients were categorized into 3 age subgroups with 10-year intervals. L1 was segmented into 9 zones, based on which, L1 was then divided into 6 regions [i.e., vBMD-anterior (vBMD-A), vBMD-medial (vBMD-M), and vBMD-posterior (vBMD-P) from the ventral to the dorsal side, vBMD-upper (vBMD-U), vBMD-medial (vBMD-M'), and vBMD-lower (vBMD-L) from the head to the foot]. Independent samples t-test, intraclass correlati
