Is QCT better than Dexa?
It is likely that the measurement of isolated trabecular bone by QCT is the reason that several studies have shown that in postmenopausal females, QCT of the spine has been found to perform as well as, if not better than, DXA in the prediction of vertebral fractures.
What does c stand for in q mc ∆ t?
The symbol c stands for specific heat and depends on the material and phase. The specific heat is the amount of heat necessary to change the temperature of 1.00 kg of mass by 1.00ºC. Q=mcΔT Q = mc Δ T , where Q is the symbol for heat transfer, m is the mass of the substance, and ΔT is the change in temperature.
What is a QCT test for osteoporosis?
Pioneered at UCSF, quantitative computed tomography (QCT) is a test to measure bone mineral density (BMD). It is performed using a computed tomography (CT) scanner and results in a 3D image. Hip and lumbar spine are the most common choices for evaluation with QCT.
What is the lowest T-score for osteoporosis?
If your T-score is:
–1 or higher, your bone is healthy.
–1 to –2.5, you have osteopenia, a less severe form of low bone mineral density than osteoporosis.
–2.5 or lower, you might have osteoporosis.

While at first glance, QCT and DXA spine BMD measurements may appear to serve the same purpose, a deeper investigation reveals each technology produces results.
The interval time between DXA and QCT scans ranged from 0 to 43 days (mean: 4.3 ± 9.7 days). The BMD of L1–L4 as measured by DXA ranged from 0.575 to 1.621 g/cm ...
In children and adolescents, QCT reports should include BMD values and Z-scores. Z-scores should be height adjusted, when possible. Z-scores above −0 are ...
