Assessment of Vertebral Bone Marrow Perfusion, Fat/Water Content, and Trabecular Bone Changes Using Multimodal MRI and Micro‐CT in a Rat Model of Chronic Kidney Disease

ABSTRACT 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–e...

description ABSTRACT 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). Methods Twelve rats were randomly separated into a normal control group and a CKD (5/6 nephrectomy) group. Their lumbar spines were imaged, with monitoring of the L5 vertebral body conducted at 0, 8, 16, 30, and 43 weeks. After Week 43, all rats were sacrificed, and histologic changes were correlated with MRI and μCT results. Results The CKD group demonstrated significantly lower A and kel values (p < 0.05), significantly increased T2* values (p < 0.05), significantly decreased fat content and trabeculation (p < 0.05), sinusoidal dilatation, and decreased adipocytes in the vertebral bone marrow. Conclusion Using quantitative MRI and μCT to assess CKD‐related arthropathy of the vertebral body is feasible. Lumbar spine bone marrow perfusion deficiency in experimental CKD may be associated with decreased fat content, increased water content, and sparse trabeculation.
