Overview
Brief Summary
Patients with chronic kidney disease (CKD) have a higher risk of fractures than those without. The purpose of this study is to develop a non-invasive Magnetic resonance imaging (MRI) method that can improve fracture risk prediction and provide early diagnosis for bone abnormalities in patients with CKD.
Detailed Description
Chronic Kidney Disease-Mineral and Bone Disorder (MBD） is a common complication of chronic kidney disease (CKD), which may lead to defective mineralization, altered bone morphology, and/or bone turnover. Animal research found that bone changes occur even in the early stage of CKD , and with CKD progression, the patient may show symptoms such as bone pain, joint pain, bone deformation, and even spontaneous fractures. Despite significant advances in understanding bone disease in CKD, most clinical and biochemical targets used in clinical practice remain controversial, resulting in an undermanagement of bone fragility.Our ability to diagnose CKD-MBD and to initiate strategies that could prevent fractures remains limited by the lack of accurate and noninvasive diagnostic tools. The purpose of this study is to develop a non-invasive method that can improve fracture risk prediction and provide early diagnosis for bone abnormalities in patients with CKD.
