There are variations on TRUS. Some are more advanced like color doppler... I don't have experience beyond color doppler, as part of a study, but some here do. I think you should try and pursue all imaging available, if you can along with biopsies in the future.
Your standard PSA is low and there are also other PSA related tests you can look into. You have an anomally that was detected on DRE. That seems it was a concern to your Uro and should be a concern for you, also. Ask your doc.
Maybe a 2nd opinion is in order?
I'm sure lot's more will chime in here.
Good luck and keep us posted.
