Magnetic Resonance Imaging (MRI) texture analysis shows promise for assessing chronic kidney disease (CKD) activity and function. This AI-driven approach correlates with estimated glomerular filtration rate (eGFR), offering a non-invasive diagnostic tool.
Area of Science:
- Radiology
- Nephrology
- Artificial Intelligence
Background:
- Current chronic kidney disease (CKD) diagnosis relies on glomerular filtration rate (GFR), proteinuria, or kidney biopsy.
- Advancements in MRI techniques and AI offer new possibilities for assessing CKD activity and kidney function through image analysis.
Purpose of the Study:
- To evaluate the efficacy of MRI image texture analysis combined with AI for assessing CKD activity and kidney function.
- To determine the correlation between MRI-derived features and estimated GFR (eGFR).
Main Methods:
- MRI scans (1.5 T or 3 T) were acquired from healthy volunteers and CKD patients.
- Patients underwent kidney biopsy for histopathological assessment of CKD activity.
- An AI algorithm was developed using T1-weighted, T2-weighted, and diffusion-weighted imaging (DWI) data.
Main Results:
- The AI algorithm achieved high sensitivity (77.78-87.50%) and specificity (86.67-94.12%) in distinguishing CKD patients.
- T1-weighted and T2-weighted MRI features showed strong correlations with GFR (coefficients -0.5922 to -0.7090 and 0.6126 to 0.6380, respectively).
Conclusions:
- MRI image texture analysis is a viable method for assessing CKD activity, independent of the MRI scanner used.
- MRI texture features demonstrate a significant correlation with eGFR values, supporting its use in kidney function assessment.

Internal Anatomy of the Kidney
Anatomical Position and Dimensions
The kidneys are retroperitoneal organs positioned against the posterior abdominal wall on either side of the spine, roughly between the twelfth thoracic and third lumbar vertebrae. Each kidney is typically 10-12 cm long, 5-6 cm wide, and 3-4 cm thick, weighing about 150 grams.
Renal Cortex
The outermost region of the kidney is the...
