Diffusion-weighted imaging in pediatric body magnetic resonance imaging

Area of Science:

• Radiology
• Pediatric Imaging
• Medical Imaging Techniques

Background:

• Diffusion-weighted MRI (DWI) is an emerging technique in pediatric body imaging.
• Its applications include detecting tumors, abscesses, and inflammatory bowel disease in children.

Purpose of the Study:

• To review the principles, techniques, and current applications of DWI in pediatric body imaging.
• To discuss the potential of apparent diffusion coefficient (ADC) values as biomarkers for therapy response assessment.

Main Methods:

• Discussion of DWI principles, b-value selection, and qualitative/quantitative assessment methods.
• Review of current literature on DWI applications in pediatric body disease evaluation.

Main Results:

• DWI is valuable for disease detection and characterization in pediatric patients.
• Apparent diffusion coefficient (ADC) values show potential for therapy response assessment but face challenges.

Conclusions:

• Widespread clinical adoption of DWI in pediatric body imaging is hindered by overlapping ADC values and reproducibility issues.
• Standardization of DWI techniques is crucial for its increased utilization in clinical practice.
