研究目的: |
通过包含 QSM、pCASL 和 BOLD 在内的多模态 MRI 肾脏功能成像后纹理特征的提取,从肾脏纤维化、血流、氧合等特征综合评估 S3b、S4 期肾功能衰竭失代偿 CKD 患者皮、髓质功能衰竭的程度,结合临床资料及实验室检查结果,通过受试者随访 2 年有无不良结局进行分组,建立不良结局的风险预测模型和列线图,弥补实验室检查不能具体、直观反映肾脏硬度、血流或氧合等功能的不足,从而达到风险评估、疾病预防和精准治疗的目的。 |

|
Objectives of Study: |
Through the extraction of texture features from multi-modal MRI renal functional imaging, including QSM (Quantitative Susceptibility Mapping), pCASL (Pseudo-Continuous Arterial Spin Labeling), and BOLD (Blood Oxygen Level-Dependent), this study comprehensively evaluates the degree of cortical and medullary functional impairment in S3b and S4 stage decompensated CKD patients with renal failure. The assessment is based on characteristics such as renal fibrosis, blood flow, and oxygenation. By integrating clinical data and laboratory test results, patients are grouped according to the presence or absence of adverse outcomes during a 2-year follow-up period. A risk prediction model and nomogram for adverse outcomes are established to address the limitations of laboratory tests, which cannot specifically and intuitively reflect renal functions such as stiffness, blood flow, or oxygenation. This approach aims to achieve risk assessment, disease prevention, and precise treatment. |

Patients who have taken anticoagulant and antithrombotic drugs (aspirin, Plavix, etc.) and diuretics within 3 days before the MRI scan, and patients who refuse medical intervention or treatment since the discovery of abnormal renal function. 3. Patients with contraindications to MRI (such as metal artifacts in the scanning area, claustrophobia, pregnancy, age < 18 years or > 70 years) are also excluded. |
