MRI Guided Biopsy

Don't you mean to ask about the "results" of the biopsy?

I had a parametric MRI with and without contrast (over 2900 images ) which showed only one suspicious spot. My urologist targeted the spot during the biopsy and it came up negative. Whereas, I did have 6 out of 13 other locations came up positive for G6 & G7.

To young.
An MRI would be a good idea, make sure it is a 3T as 1.5T MRIs are pretty useless for prostate imaging. Your psa trend of a .6 rise over a 1/12 period is consistent for low risk PC which your first biopsy discovered. The MRI will not pick up small tumors and this is a good thing, but it will pick up anything large enough to cause you harm.
Imaging tumors will affect your treatment choice by determining the size and location of any tumor. Tumors located at the margin, in the apex of near the nerves are better treated by some form of radiation as these areas carry a higher risk of surgical failure. Small tumors in the center of the prostate can be watched safely for many years.

toyoung Choice of treatment as has been said over and over again here and in white papers, depends on the BX, age, health and expected lifespan of the patient before PCa was Dxd. If subsequent BX discloses more aggressive PCa  the treatment (if any) may  change, but it may not. Clearly getting the most accurate BX available is VERY important. Unfortunately, ONLY RP tells you exactly what you have, but it's a potential big price to pay for that knowledge. ED is usually a significant issue with RP, (especially for younger men) whereas incontinence may or may not be an issue at all. At age 51, (which is young to have PCa), low volume PCa and low Gleason score, AS makes a lot of sense for you.  Some guys go ahead with treatment with GL 6 and some don't. It depends to a large  extent on their ability to live with PCa psychologically, knowing it may be spreading while they wait. Since you're young, retention of sexual capability is usually very important, so I would stay away from RP for now. If anything, I would chose brachytherapy. Even if the next Bx is Gl 7, I would do so.  It's up to you. Good luck and I hope your good stats continue!!!
