To date, dual-energy X-ray absorptiometry (DXA) and vertebral morphometry are the recommended examinations to evaluate bone health in these patients, despite known limitation. Calcaneal quantitative ultrasound (cQUS) is a less expensive and less invasive method to evaluate bone status compared to DXA. We aimed to investigate bone status by cQUS in a cohort of patients with acromegaly and to evaluate its ability to detect bone impairment.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Observational cohort study including 56 patients with acromegaly (acromegaly group, AG) and 59 healthy subjects matched for age, sex and BMI (control group, CG).

The cQUS-derived T-score showed a good discriminatory ability for the presence of osteopenia in the AG (AUC 0.833 [CI 0.721-0.945]).
