Hi, My liver shows biliary ductal dialation greater than previously reported, now 9mm. The report says "Biochemical correlation advised". What does that mean? Does the radiologist want me to have another test to see what's going on? If so, what kind of test? I've just lost 70 lbs in the last year and do not have any problems with my liver. I also reversed my Type 2 diabetes and was taken off blood pressure meds also.
