Overview
Imaging is often ordered in the workup of suspected NAFLD.Problematically, ultrasound of fatty liver reveals a hyperechoic echotexture - a so-called 'bright liver' - that can often be indistinguishable from fibrosis and generally cannot reliably delineate NAFLD from NASH. CT scan may be helpful in the diagnosis of complications of NAFLD, which include the structure of the liver. But using CT is limited because of the exposure to ionizing radiation. [1]Contrast enhanced CT has a sensitivity up to 84-87% and specificity of 75-86%.
CT scan
- CT without contrast is an effective test for elavating liver strucutre and liver fat content.[2]
- CT with contrast has less senstivity and specifcity and has additional risk of the contrast exposure
