Renal osteodystrophy (ROD) refers to alterations in bone turnover, mineralisation, mass and microarchitecture in patients with chronic kidney disease (CKD) and represents the skeletal component of ‘CKD–mineral and bone disorder’. Changes in bone structure lead to impaired bone quality, compromised bone strength and increased susceptibility to fractures with associated significant morbidity, mortality and financial cost. Diagnosis and management of ROD is hindered by the inadequacy of currently available diagnostic methods to interpret the complex pathophysiology. Bone biopsy, the perceived gold standard test to assess ROD, is invasive and suboptimal for disease screening and management in routine clinical practice. High‐resolution imaging, such as high‐resolution peripheral quantitative computed tomography and high‐resolution magnetic resonance imaging provide accurate non‐invasive quantification of bone microarchitecture and facilitate assessment of mechanical competence of bone, correlating with skeletal fragility. We discuss the potential for these imaging techniques in patients with CKD to provide quantification and assessment of bone structure and strength. When used in conjunction with serum biomarkers, these investigative tools may provide a non‐invasive diagnostic virtual bone biopsy.
