Background: Disturbances in calcium and phosphorus homeostasis resulting from chronic kidney disease (CKD) may lead to atherosclerotic changes in blood vessels, potentially altering bone marrow perfusion. Our study aimed to investigate vertebral bone marrow perfusion using dynamic contrast-enhanced (DCE) MRI with a pharmacokinetic model. We also measured possible changes in water and fat content and bony trabeculae using T2* quantification, MR spectroscopy (MRS), and microcomputed tomography (μCT).
