Dynamic-contrast enhanced MR imaging is widely employed as a clinical tool in kidney imaging and renal function measurements. Some novel works have been made in improve temporal resolution. In this work, we adopt a 3D Cartesian MRI with compresses sensing and variable view sharing sequence to explore its evaluation in renal embolism assessment. GFR was calculated and renal embolism was confirmed by histological results. Fast DCE-MRI is a promising method for renal embolism diagnose.
