QCT OSTEOPOROSIS SCREENING

QCT-Bone Densitomitry uses our CT scanner to quantitatively measure trabecular bone in the spine. The high diagnostic accuracy of QCT is due to CT’s 3-dimensional imaging capability which allows precise separation of the highly active trabecular bone from the more dense, slowly changing cortical bone.

Why measure Bone Density in the spine with QCT?

Osteoporotic fractures tend to occur first in the vertebral bodies.

The vertebral bodies are composed primarily of trabecular bone.

Trabecular bone is affected earlier than cortical bone.

Trabecular bone has a turnover rate much higher than cortical bone, thus making the spine an ideal site for measurement of osteoporosis and for assessing treatment.
