endorectal mri

We have heard encouraging reports about color doppler as a diagnostic device for prostate cancer. How about endorectal mri? Has anybody had success with this mri in identifying pca in cases where regular biopsies failed?

I had an MRIS at UCSF after 11 negative biopsies. It come up clear. After another negative biopsy I had two color doppler ultrasounds and both showed a large tumor which was biopsied as positive.
I asked my doctor about the negative MRIS and he said it was good at picking up cancers near the surface of the prostate, but was not good at seeing tumors that were in the interior.
I also asked Dr Barantsz, the leading researcher in prostate cancer imaging, and he said that Telsa 1.5 MRIs were not very good at spotting tumors and you need at least a Telsa 3.
I think that the biggest advantage of a color doppler is that you can immediately biopsy any suspicious area and actually see the biopsy needle track to see if you hit it. With an MRIS if a suspicious area is located you must go in for a biopsy and there is no way they can tell if the tumor was hit as they can only biospy the general area and not a specific spot. With a color doppler samples are taken from the edges of the tumor and also from the center so you get a real good idea of it's gleason composition. If a bopsy just hits the edge it can appear to be a gleason 6 where as the center is a G7. This is exactly what happened in my case.
