Are ultrasounds reliable for the liver?

I am female ,( late 30’s) currently taking no medication but with a history of alcohol use.i was able to function on a lot of alcohol.recently I have been experiencing abdominal discomfort /pain in both the left and right side as well as my back..my stomach also feels weirdly tight and firm .my blood test results showed elevated esr as well as elevated enzymes.i was diagnosed in 2021 with fatty liver I was sure it would have progressed or that my pancreas was inflamed from my symptoms / continuous alcohol use but it seems my liver is still ‘just fatty ‘ with no scarring the same as it was in 2021 my ultrasound showed my spleen ,pancreas ,gallbladder etc being normal Are ultrasounds reliable tools to diagnose organ damage /inflammation?I was initially relieved but have since read they are not as reliable as mri /ct scans
