@petuniamom567 Yep, I have been in your shoes!

In my situation, my MRI was for a non-kidney related issue. However, seeing my eGFR was less than 30 already, so we opted to go with no contrast, For me, it wasn't worth the risk of going into kidney crisis with the dye. I was given the choice same as you. I closely questioned the ordering physician, to see what the difference would be if we went with a contrast or non-contrast MRI. In our opinion, the difference wasn't enough to take the risk. He had been leaning towards non-contrast, but wanted my input, which I appreciated!

Like you, I have some cysts on my right kidney. Recently, what they thought was a renal cell carcinoma tumor, was determined to be a "complicated cyst". The urologist told me he felt due to not seeing a movement of blood through the mass, it was a cyst rather than tumor.

Here is what Mayo Clinic has to say about kidney cysts: https://www.mayoclinic.org/diseases-conditions/kidney-cysts/symptoms-causes/syc-20374134
And what Cleveland Clinic has to say: https://my.clevelandclinic.org/health/diseases/14884-kidney-cysts

Will you please let me know what you decide. I'm interested!
