Post-contrast enhancement: Pelvic MRI findings

So, I just got back from getting an MRI on my pelvis, and apparently, there’s a cyst on one of my ovaries—not just a simple fluid-filled thing, but something with a thicker, denser structure inside. The report also mentions some kind of "post-contrast imbibition," which sounds incredibly fancy and intimidating. Does anyone here actually know what that means in plain English?
