It did for me, but I don't think that is common. For some reason contrast seemed less effective for me over time, I doubt that is your case. I guess it is always a possibility, probably a very low probability, so how to communicate that to the radiologist to double check the diffusion weighted images if the Pirads rating done with contrast is falling, that I don't know since we almost never see or hear from them. They should be looking at diffusion weighted images, but most don't seem to bother since contrast seems to do the job.
