Representative 3-dimensional reconstruction images of HR-pQCT of a 6-year-old male patient with SLC4A1-dRTA, a sex- and age-matched XLH patient, and healthy control. Compared to the healthy control, the bone cortex of the distal radius and tibia were thinner, and bone trabeculae were sparser in the SLC4A1-dRTA patient and XLH patient.

Abbreviations: Ct, cortical bone; dRTA, distal renal tubular acidosis; HR-pQCT, high-resolution peripheral quantitative computed tomography; Tb, trabecular bone; XLH = X-linked hypophosphatemia.
