The Evolution of Prostate Multiparametric MRI and Its Application in Prostate Cancer Clinical Management

Area of Science:

• Radiology
• Oncology
• Medical Imaging

Background:

• Prostate cancer (PCa) diagnosis relies heavily on multiparametric MRI (mpMRI).
• mpMRI integrates T2-weighted imaging (T2WI), diffusion-weighted imaging (DWI), and dynamic contrast-enhanced MRI (DCE-MRI).
• Accurate mpMRI interpretation is vital for clinical decision-making in suspected PCa cases.

Purpose of the Study:

• To review the preparation techniques, evolution, and current technologies of prostate mpMRI.
• To explore the clinical applications of diffusion tensor imaging (DTI) in radical prostatectomy planning.
• To assess the potential of biparametric MRI (bpMRI) and address PI-RADS category 3 lesions in PCa diagnosis.
• To discuss the current status of MRI-ultrasound fusion targeted biopsy for PCa.

Main Methods:

• Comprehensive literature review of prostate mpMRI techniques and applications.
• Analysis of diffusion tensor imaging (DTI) for surgical planning.
• Evaluation of biparametric MRI (bpMRI) in PCa diagnosis.
• Review of PI-RADS criteria and MRI-ultrasound fusion biopsy techniques.

Main Results:

• mpMRI preparation and advanced techniques are critical for accurate PCa detection.
• DTI shows promise for guiding radical prostatectomy.
• bpMRI offers a potential alternative, but challenges remain for PI-RADS category 3 lesions.
• MRI-ultrasound fusion biopsy improves the accuracy of targeted biopsies.

Conclusions:

• Prostate mpMRI, including advanced techniques and fusion biopsy, is essential for PCa management.
• Continued research into bpMRI and PI-RADS criteria is needed.
• Optimizing mpMRI protocols and interpretation enhances diagnostic accuracy and patient outcomes.
