What This Test Measures
This test evaluates a radiographic index derived from bone scans to assess how cortisol exposure might affect bone mineral density (BMD). It is not a standard clinical test but may be used in research or specialized clinical settings to study bone metabolism indirectly through imaging.
Why It Might Be Ordered
Your healthcare provider may order this test if they suspect cortisol-related bone changes, particularly in conditions like Cushing’s syndrome, long-term steroid use, or research studies investigating bone density and hormonal effects.
How the Test Works
A bone density scan (often a dual-energy X-ray absorptiometry, or DXA scan) is performed to capture images of bone structure. The radiographic index is calculated from these images to assess potential changes in bone mineral density influenced by cortisol levels.
Preparation for the Test
No special preparation is typically required. You may need to fast for a blood draw (if cortisol levels are also measured) or avoid certain medications, but this test specifically focuses on imaging. Follow your provider’s instructions for any related blood or imaging tests.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions
Cortisol is a hormone that affects bone metabolism. High cortisol levels (from conditions like Cushing’s syndrome or long-term steroid use) can lead to bone loss over time. This radiographic index helps evaluate whether cortisol exposure may contribute to changes in bone density, though it is not a direct measurement of cortisol itself.
