I have had over 20 MRI with Gadolimium over the years due to non prostate cancer surveillance. Along with several for prostate. I am trying to reduce gad exposure. I understand that there are some urologists and med centers starting to use non contrast MRI for surveillance along with AI software. I have single small lesion PIRADS 4 that was biopsies multiple times with Negative results. Looking to track growth and feature changes if any to make biopsy decisions in future. I am in east cost New York / CT region. But willing to travel. Thx.
