Physicians typically measure two areas—the spine and hip—and then compare your actual bone density to the density your bones should be to resist breaking (which is the bone density of a 30-year-old). The result is a measurement called a “T-score.” Both the p-DEXA and central DEXA use a “T-score” to indicate your level of bone density but the results are used differently. Your physician will use the T-score and a skilled analysis of your scan to make an accurate diagnosis.

Note: You might see a Z-score on your report, but it is not a proper number to use for diagnosis.
