Quantitative ultrasound of the calcaneus in long-term liver or cardiac transplantation patients.

Bone loss is one of the most common complications after solid-organ transplantation, but it is frequently under-diagnosed. Our purpose was to evaluate quantitative ultrasound of calcaneus (QUS) in comparison with dual-energy X-ray absorptiometry (DXA) to identify transplant recipients with osteoporosis. We have cross-sectionally evaluated 140 transplant recipients (85 liver and 55 cardiac transplantations; mean age: 53.
