Functional MR imaging of the abdomen

Area of Science:

• Radiology and Medical Imaging
• Abdominal Imaging
• Functional MRI

Background:

• Functional magnetic resonance (MR) imaging offers advanced insights into abdominal organ function.
• Standard MR imaging can be limited in characterizing certain pathologies.

Purpose of the Study:

• To review the applications of various functional MR imaging techniques in abdominal organs.
• To highlight the potential of these techniques in diagnosis and treatment monitoring.

Main Methods:

• Discussion of diffusion-weighted imaging (DWI) for hepatic lesions.
• Outline of DWI applications in kidneys, adrenal glands, bowel, and pancreas.
• Review of quantitative dynamic contrast-enhanced MR imaging (DCE-MRI) parameters (e.g., K(trans)).
• Consideration of MR elastography for liver fibrosis staging.

Main Results:

• DWI enhances confidence in detecting and characterizing focal hepatic lesions.
• Quantitative DCE-MRI parameters show potential in predicting cancer therapy outcomes.
• MR elastography is a valuable tool for staging liver fibrosis.

Conclusions:

• Functional MR imaging techniques provide valuable diagnostic and prognostic information for abdominal diseases.
• Standardization of protocols remains a critical challenge for widespread adoption.
• These advanced MR techniques hold significant promise for improving patient care in abdominal imaging.
