Conditions

Renal malignancy or chronic kidney disease

Interventions

Gold Standard:1. Pathological diagnosis of renal malignant tumor or chronic nephritis

2. Routine MRI, PGSE, and OGSE scans were performed within 2 weeks before pathology examination.

Index test:T2-weighted imaging (T2WI), T1-weighted imaging (T1WI), diffusion weighted imaging (DWI), OGSE, PGSE and contrast-enhanced scanning. Three quantitative parameters Dex, D and Vin were derive

Inclusion criteria

Inclusion criteria: 1. Pathological diagnosis of renal malignant tumor or chronic nephritis; 2. Routine MRI, PGSE, and OGSE scans were performed within 2 weeks before pathology examination.

Exclusion criteria

Exclusion criteria: 1. Patients with renal tumors or chronic nephritis who had received treatment before PGSE and OGSE sequence scanning; 2. Patients who received renal aspiration within 2 weeks prior to PGSE and OGSE sequence scanning; 3. Post-processing of PGSE and OGSE sequences cannot be carried out due to poor image quality caused by motion artifacts or other reasons.
