For patients and public
In centres with high-quality MRI and experienced radiologists, a shorter scan without contrast performs as well as the longer contrast scan. Overall, bpMRI can shorten appointments and remove the need for a cannula, helping more people get the scans they need.
No difference in finding important or unimportant cancers
No increase in the number of men advised to have a biopsy
No differences in false positives / specificity
Only minor differences in treatment decisions
