Clinical Trial Summary

In this project, IDEAL-IQ technology and PDFF and R2* image-based imaging methods are used to analyze the intrinsic relationship between preoperative vertebral bone marrow fat content, magnetic susceptibility properties of bone tissue and bone strength (bone volume and bone mass), to explore the mechanism of vertebral re-fracture after PVP / PKP, and to explore the imaging markers for the risk of postoperative vertebral re-fracture after PVP / PKP. To construct a precise and individualized risk assessment model of vertebral re-fracture after PVP/ PKP by combining clinical risk factors, preoperative quantitative MRI parameters (PDFF, R2*) and imaging characteristics, so as to achieve the goal of objectively and accurately evaluating the risk of vertebral re-fracture at the early stage of the postoperative period (1 year).
