I had a ultrasound and I may have fatty liver. If I would go for MRI to confirm the diagnosis, should the MRI be with or without contrast? Thank you

CT is next step. Ct of the abdomen without contrast is an accurate and more economical method for confirming fatty liver.
Without. Well I am going to confuse you even more. To simply diagnose fatty liver, contrast is not necessary. However, if you get an MRI of the liver, contrast injection is necessary to diagnose most major concerns including cancer.
Depends. A fatty liver is usually not a concern but it may hide other disease. An MRI is indicated only if there is a concern for other liver problems. In that case, contrast is recommended.
