Diffusion weighted imaging of the prostate-principles, application, and advances.

Area of Science:

• Radiology
• Oncology
• Medical Imaging

Background:

• Prostate cancer (PCa) diagnosis and management rely heavily on accurate imaging.
• Diffusion-weighted magnetic resonance imaging (DW-MRI) has emerged as a key technique for prostate evaluation.

Purpose of the Study:

• To review the fundamental principles of DW-MRI.
• To outline the diverse applications of DW-MRI in prostate imaging.
• To discuss emerging DW-MRI techniques.

Main Methods:

• Review of existing literature on DW-MRI principles and prostate applications.
• Discussion of DW-MRI's role in PCa detection, characterization, and staging.
• Presentation of advanced techniques such as diffusion kurtosis imaging (DKI).

Main Results:

• DW-MRI is crucial for prostate cancer detection and characterization.
• It aids in local staging and monitoring active surveillance (AS).
• DW-MRI is effective in identifying tumor recurrence post-radical prostatectomy (RP).

Conclusions:

• DW-MRI is an indispensable tool in modern prostate cancer management.
• Ongoing advancements, including DKI, promise to further refine its clinical utility.
• This review provides a comprehensive overview for clinicians and researchers.
