Abstract
Objective
To develop a simplified method to quantify liver fat using computed tomography (CT)
fat % index (CTFPI) compared to liver spleen method (CTL/S, CTL−S).
Methods
Noncontrast CT of the liver was performed in 89 patients (overweight, obese, severely
obese) to quantify fat, using the following: CTFPI=[(65−patient HU)/65]×100, normal live r=65 HU.
Results
There was a strong linear correlation between CTFPI and the standard method of assessing liver fat using CTL/S (r=−0.901), CTL−S (r=−0.911). Hepatic HU and CTFPI were significantly different in the severely obese group compared to other two groups
(P<.05).
Conclusion
Significant correlation indicates equal diagnostic accuracy of the two methods in
appropriately calibrated scanners.
