Thanks again all,
I had an MRI with endorectal coil this morning along with a 3D and advanced ultrasound. It's part of a study I agreed to participate in (mentioned earlier in this thread). It won't help me but, I hope it helps others if imaging diagnostics can be improved for PCa.
The endorectal MRI: Was a little uncomfortable going in (the coil) but, no problem at all. Pain level far less than 1 (mild discomfort about same as DRE for me). I had it in about 45 minutes while the MRI was humming away. Just needed to lie still. Had a DRE before insertion of MRI probe and nothing to be concerned about. Everything was well lubricated and they even can me a topical pain killer. I didn't even have that with the TRUS biopsy in November. In hindsight, that wasn't that bad either.
The TRUS (3D): This was about 20 minutes after MRI finished and again, no problem. Although already intruded upon rectally, just mild discomfort going in. The probe was in about 20 minutes and I was more interested in what was happening on the display and my discussion with the radiologist, than anything else.
This study includes a lot of US and Canadian centers. If your surgeon asks you to participate, it may well help the next guy.
Even the laxative to clear out the large bowel was no problem. Actually, the only problem was a wet spot due to the residual lubricants...made cornering easy on the drive home.
Friday is CT day and no prep needed for that.
