Examples are 0.9, 0 and -0.9.A T-score between -1.0 and -2.5 means you have low bone density or osteopenia. … A T-score of -2.5 or below is a diagnosis of osteoporosis. … The lower a person’s T-score, the lower the bone density.

What can a bone scan detect?

Your doctor may order a bone scan if you have unexplained skeletal pain, a bone infection or a bone injury that can’t be seen on a standard X-ray.
