Fatty Liver on Ultrasound: What 'Bright Liver' and the Grades Mean

If your ultrasound mentioned "fatty liver", "steatosis" or "bright liver", this educational guide explains what the specialist saw and why it matters —even if you feel fine and your labs are normal.

The "bright liver" pattern

Fatty liver on ultrasound is recognized because the tissue reflects sound more and looks whiter and brighter than normal. The specialist compares it with the kidney: if the liver is clearly brighter than the renal cortex, it suggests fat (steatosis).

The grades of fatty liver

• Mild (grade I): subtle brightness, structures still visible.
• Moderate (grade II): obvious brightness, vessels less sharp.
• Marked (grade III): intense brightness, deep area hard to see.

Why it appears even when blood is normal

Many people with fatty liver have normal transaminases (ALT/AST). Metabolic change accumulates silently inside the cells before altering the blood. Imaging detects that fat directly, which is why ultrasound is such a useful complement to lab work.

How it relates to insulin resistance

Fatty liver often accompanies insulin resistance and prediabetes. Understanding this connection —how liver metabolism relates to energy and hormones— is the core of the Salinas Method's educational approach.
