Diffusion Weighted Imaging of the Abdomen and Pelvis: Recent Technical Advances and Clinical Applications

Area of Science:

• Radiology and Medical Imaging
• Biomedical Engineering

Background:

• Diffusion weighted imaging (DWI) is crucial for abdominal and pelvic imaging, particularly for detecting malignancies.
• Single-shot DWI techniques face limitations due to image distortion and artifacts, hindering clinical application.

Purpose of the Study:

• To review recent technical advancements in abdominopelvic DWI.
• To highlight future perspectives and potential research directions in the field.

Main Methods:

• Review of recent technical improvements in DWI, including simultaneous multi-slice excitation, reduced field-of-view techniques, and advanced shimming.
• Discussion of how these methods address limitations of conventional DWI.

Main Results:

• New DWI techniques enable shorter acquisition times.
• Improved image quality and robustness in abdominopelvic DWI are achievable.
• Overcoming limitations of single-shot DWI is possible with advanced methods.

Conclusions:

• Recent DWI advancements offer improved image quality and robustness for abdominal and pelvic imaging.
• Physicians and radiologists can benefit from familiarizing themselves with these technical improvements.
• Further research is encouraged to explore the full potential of advanced DWI techniques.
