The Results of Your Scan
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.
