A TPS report (" test procedure specification ") is a document used by a quality assurance group or individual, particularly in software engineering, that describes the testing procedures and the testing process.

2021年6月22日 · Trabecular Bone Score, or TBS, is a computer software application that is installed on DXA machines. The program takes the DXA image of the lumbar spine (low back) …

2015年11月25日 · Trabecular bone score (TBS) uses standard lumbar spine DXA imaging to assess bone texture inhomogeneity (that is, the number of filled versus unfilled voxels) in order to gauge bone quality and fracture risk.

The TBS is derived from the texture of the DXA image and has been shown to be related to bone microarchitecture and fracture risk. It provides information independent of BMD.

Relative Risk of TBS expressed by standard deviation and compared with relative risks of major clinical risk factors for fracture The trabecular bone score is a textural parameter that can be applied to DEXA, which quantifies the local variations in gray level.

The combination of TBS and BMD allows refining the fracture risk analysis, particularly in osteopenic patients. It results the following concept of interpretation table, with risk levels expressed as a number of major osteoporotic fractures per 1’000 women/year:

2023年7月21日 · A new position paper presents an up-to-date review and expert recommendations using the GRADE methodology to inform the implementation of trabecular bone score (TBS)* in clinical practice for the management of primary and secondary osteoporosis.1

TBS 3.1 has been updated with new tools and reporting added including: A skeletal status assessment table was added, providing a “Bone Resilience Index” that visually shows the combined BMD T-score and TBS categories.

Trabecular bone score (TBS) is an indirect and noninvasive measure of bone quality. A low TBS indicates degraded bone microarchitecture, predicts osteoporotic fracture, and is partially independent of clinical risk factors and bone mineral density (BMD).

index of bone microarchitecture that provides skeletal information complementary to that obtained from standard bone mineral density (BMD) measurement.
