Hi @formayor, first and foremost, I wish you and your wife and family a quick and complete resolution to whatever the issue turns out to be. Yes, we have found CTs to be inconclusive as well. We have found liver MRIs to be more useful in terms of identifying "lesions" that may be in the liver, their size and prominence, and potentially whether they are cancerous or not. Based on my understanding, they can only be determined for cancer if they are large enough to be needle biopsied.
I have initiated the process to have a liver specialist see my mom, per @colleenyoung's advice above (thank you, @colleenyoung!). I will post any findings to this string and hope you find it useful for your wife. In the meanwhile, please let me know if you have further questions about our journey so far, just to compare notes.
