3T magnetic resonance diffusion tensor imaging in chronic kidney disease

Area of Science:

• Nephrology
• Radiology
• Medical Imaging

Background:

• Chronic kidney disease (CKD) affects millions globally, necessitating advanced diagnostic tools.
• Current methods for assessing renal function can be invasive or lack sensitivity to early structural changes.

Purpose of the Study:

• To explore the correlation between apparent diffusion coefficient (ADC) and fractional anisotropy (FA) values derived from 3T diffusion tensor imaging (DTI) and renal function in patients with CKD.

Main Methods:

• Diffusion tensor imaging (DTI) was performed on 29 patients with CKD and 20 healthy volunteers using a 3T MRI scanner.
• Analysis focused on the relationship between renal ADC and FA values and standard markers of renal function, including serum creatinine and blood urea nitrogen.

Main Results:

• Patients with CKD exhibited significantly lower cortical and medullary ADC and FA values compared to healthy controls (P = 0.000).
• Both renal ADC and FA values demonstrated a significant inverse correlation with serum creatinine and blood urea nitrogen levels (P < 0.05), indicating reduced diffusion and altered tissue microstructure with declining kidney function.

Conclusions:

• Diffusion tensor imaging (DTI) is a feasible and non-invasive imaging technique.
• DTI parameters (ADC and FA) can effectively reflect the severity of renal function impairment in chronic kidney disease.
