Conclusion
Diffusion-weighted imaging (DWI) is a powerful noninvasive imaging method that may yield useful qualitative and quantitative information about tumor cellularity and tissue structure in prostate cancer and permits detecting and staging prostate carcinoma.
A pretreatment combination of tumor ADC,
Gleason score and baseline PSA level might play an important role in risk staging for prostate cancer treatment,
which could improve the cancer control while reducing risks of treatment-related complications.
This would lead to a major change beyond the role of MR imaging such as tumour detection and staging in prostate cancer
Additionally,
it may be a useful tool to monitor the therapeutic effects of prostate cancer after hormonal or radiation therapy and for guiding targeted biopsy in patients with previously negative biopsy results.
DWI used in conjunction with T2-weighted imaging improve the detection of local recurrence after RT,
HT or radical prostatectomy and facilitates the detection lymph node metastasis an hematogeneous metastases (bone and liver).
