Key result
Detecting fatty liver on CT CAC scans feasibly identifies increased cardiovascular risk.
Fatty liver can be determined from CT coronary artery calcium scoring acquisitions, providing additional prognostic information for cardiovascular risk.
May support opportunistic fatty liver assessment on CAC CT; leaves open incremental prognostic value pending prospective validation.
Nonalcoholic fatty liver disease may range from simple steatosis to fibrosis and cirrhosis. It is associated with the development of coronary artery calcification and appears to be an independent predictor of future adverse cardiovascular events. As the presence of a fatty liver appears to portray an independent increased risk, it may be beneficial to note this on coronary artery calcium scoring reports. Determination of fatty liver is relatively easy to perform. We discuss the method used by the Multi-Ethnic Study of Atherosclerosis (MESA) study for determination of fatty liver from CT coronary artery calcium scoring acquisitions, which may be implemented in clinical analysis.

Kerut et al. (2017) conducted a review in Nonalcoholic fatty liver disease. CT coronary artery calcium scoring for fatty liver determination was evaluated. Determination of fatty liver from CT coronary artery calcium scoring acquisitions is a feasible method that may be implemented in clinical analysis to identify increased cardiovascular risk.
