Multimodal Imaging Assessment of Chronic Kidney Disease Patients at Different Stages From a Cardio-Renal Interaction Perspective

"Tracer: \^18F FAPI 04 is used in this study. A single intravenous bolus dose of 3.70-4.44 MBq/kg is administered.~• Simultaneous PET/MR Acquisition: During PET imaging, cardiac MR (CMR) is performed in the supine position. All images are acquired with ECG gating and respiratory gating, during end expiratory breath holds.~1. Cardiac Morphology and Function (Localization \& Cine):Assess cardiac structure and global/regional function~2. T2 Weighted Fat Suppressed Imaging:Evaluate myocardial edema~3. First Pass Perfusion Imaging:Quantitatively assess the extent and severity of myocardial perfusion defects~4. Late Gadolinium Enhancement (LGE): Detect and quantify myocardial necrosis and fibrosis~5. T1 Mapping (Pre and Post Contrast): Quantify myocardial interstitial fibrosis~6. T2 Mapping (Pre Contrast):Quantify myocardial edema~7. Cardiac PET Imaging:Evaluate myocardial fibrosis characteristics using \^18F FAPI PET data"
