Sample Spine TBS (Trabecular Bone Score) Report

The trabecular bone score (TBS) is a textural measurement derived from lumbar spine dual-energy X-ray absorptiometry (DXA) images. It is an
index of bone microarchitecture that provides skeletal information complementary to that obtained from standard bone mineral density (BMD) measurement. A software tool called TBS iNsight installs on existing DXA scanners and determines the TBS score by estimating fracture risk based on bone texture (an index correlated to bone microarchitecture) in addition to risks determined by DXA bone density and clinical risk factors. The patient doesn't receive any additional radiation dose. The inclusion of a TBS score report together with a bone density report offers the following advantages:

■  It's a better predictor of fracture risk than DXA scores alone.

  The TBS score is unaffected by abnormal bony outgrowths (osteophytes) on the spine of arthritic patients. In contrast, bone density scores of the spine are often abnormally high in people with osteoarthritis of the spine.

  The TBS score is a better indicator of bone strength than a bone density T-score.

■  TBS determinations have high reproducibility with values ranging from 1.1% - 1.9% C.V.

  The TBS report is generated simultaneously with the standard DXA spine printout so it's fast and doesn't involve any extra time.

The images below show examples of dense and porous trabecular bone in vertebrae. This is what the TBS software measures.
