**3.4 Noninvasive assessment of NAFLD**

### *3.4.1 Imaging assessment*

Every study participant was performed high-resolution real-time duplex ultrasonography with semiquantitative assessment of steatosis as follows: mild, moderate, and severe [21]. Point shear wave elastography was performed in order to rule out severe fibrosis (F4) [22]. Each patient also underwent abdominal helical computed tomography (CT) with evidence of the decrease of liver density consecutive to lipid accumulation [23].
