Question: Does preoperative mp-MRI of the prostate provide little information about staging of prostate carcinoma in daily clinical practice?
Answer: In routine clinical practice, mp-MRI at non-academic centers has very limited clinical value in predicting ECE and SVI. Our data support the current recommendations against the widespread preoperative use of mp-MRI because it is not adding reliable predictive information on the extent of prostate cancer.
Output:
yes
