I have a question about other people's experiences with CT scans for finding kidney tumors (and anything else that probably shouldn't be in there - other than loose change, car keys, etc..)
I recently had a set of ultrasounds about 6 months apart that showed a growing mass in my left kidney. After the second one I had a cat scan done to confirm the results of the ultrasound. Because I have high creatinine levels and compromised kidney function (low eGFR) my nephrologist said to do the cat scan without a contrast dye because to use contrast could cause kidney failure. I was to use an oral barium contrast only, which highlights the digestive system but not any other organ tissues - from what I understand.
The results of the scan came back "negative", with the understanding that that because there was no contrast, they couldn' be 100% certain that a mass wasn't there. The mass as measured on the ultrasound was less than 4 CM, so it was not a large one.
My question for all is this: has anyone else had a similar experience and it turned out to be positive without contrast, either during the scan or at a later time? If so, do you recall the size of the tumor?
I would also like to hear any anyone else's stories regarding the use of contrast if they have high creatinine and/or low eGFR.
Or if you just want to say hi, that's ok too :-)
Thanks for reading and I look forward to your replies.
