The QCT Pro™ Advantage

If you need bone densitometry, have access to a CT scanner with five minutes per-patient capacity, a desire for the best technology and the most cost-effective solution, then QCT Pro™ is for you.

QCT Pro™ transforms your CT scanner into a bone densitometer with the best of both worlds: QCT trabecular spine BMD for sensitive early-detection of low bone mass; and DXA-equivalent hip BMD for use in the diagnosis of osteoporosis and low bone mass, as well as fracture risk assessment.

QCT Pro™ is the first system to exploit CT’s inherent advantage for true 3-dimensional densitometry with volumetric BMD of the spine and hip. Volumetric BMD is faster, easier, clinically superior, and enables new densitometric capabilities not within the reach of DXA.

QCT Pro’s scanner-independent, Windows® -based design enables clinicians and researchers without CT scanners access to QCT. QCT scans can be performed at any CT site and the data transferred to any PC running the QCT Pro™ system (via various methods such as network or CD) for convenient analysis and diagnostic control.

QCT Pro™ is the sensible financial investment in addition to the performance choice. DXA simply cannot compare with QCT Pro™ with its low purchase price and no site, room, personnel or recurring maintenance costs. Over the life of the solution, the cost of QCT Pro™ is a small fraction of DXA.

The Spine Volumetric BMD Advantage

QCT’s ability to assess trabecular, volumetric mineral density, independent of cortical bone, has long been recognized as advantageous because of the high metabolic activity of trabecular bone relative to cortical bone.

The 3D Imaging Advantage

3D Volumetric Spine offers volumetric data sets that take you beyond the limitations of DXA’s planar technology. This application boasts exceptional sensitivity to short-term bone density changes and the ability to assess BMD in patients with complex spinal deformities.

Only quantitative CT techniques of measuring bone density in the axial or peripheral skeleton, which measure actual volumetric density, can provide a true assessment of bone density when calibrated correctly. Other methods including SXA, DXA and radiographic absorptiometry (RA) only provide estimates of true bone density. Because they are projectional techniques, the true value of the depth of the skeletal region is not measured, and an expression of area density (in gm/cm2) is generated. Parameters of ultrasound transmission velocity or attenuation may reflect both bone mass and bone architecture and cannot be truly calibrated against a bone mineral standard.

Thus, besides QCT, none of these techniques provide truly accurate measurements of “bone density.”
