[|Human|] I had a ultrasound done of my liver, found a whitish area the size of 5.4 cm on my right lobe, I clearly saw it with my own eyes, now I had a MRI done and doctors say theres nothing on my liver when you can clearly see it on an ultrasound. Im 21 weeks pregnant. What can it be or why cant they see anything on the MRI?
[|AI|]  Hi, thank you for posting. You don't have to worry... Ultrasound is a widespread method all over the world. It is cheap, fast and harmless method. But it is not an exact method. Ultrasound images sometimes are fallacy, like in your case. An ultrasound technician with work experience can easily find mistakes. MRI is a sophisticated and exact method. If MRI is negative, there is no reason to worry about. Regards.
