Signatera Test. Is it truly helpful and worthwhile?

Hi. I’m not sure why this post is in this discussion. The Signatera test is a blood test not an imaging test. But since it’s here I’d like to ask about the 2 pints of contrast liquid you are drinking. I’ve had about a dozen Ct scans in Italy with the intravenous contrast but nothing to drink. Very curious.

I guess I was trying to comfort the lady who expressed anxiety about upcoming CT scan, so that’s why I mentioned it. I actually don’t know why we get the 2 pints, I see everyone in the waiting room drinking them. I didn’t know other countries don’t do the same. Maybe different CT machines? (Of course there are CT’s without contrast too.) I’ll ask at my next appointment ….

I can answer that. For my chest CT I only have IV contrast but I have to drink the liquid for my abdominal and pelvis CTs. They can do those with IV but the radiologist told me the liquid gives much better images for GI CTs.
