Novel multi-parametric diagnosis of non-alcoholic fatty liver disease using ultrasonography, body mass index, and Fib-4 index

Figure 3 Receiver-operating characteristic curve for each parameter. This shows the receiver-operating characteristic (ROC) curve of the 17 patients who underwent liver biopsy during the period of this study. The areas under the ROC curves (AUROCs) of shear wave speed, dispersion slope, attenuation imaging value, body mass index, Fib-4 index, and the area of the non-alcoholic steatohepatitis (NASH) pentagon are 0.88000, 0.82000, 0.58730, 0.63000, 0.59333, and 0.93651, respectively. Of these six parameters, the largest AUROC is that for the area of the NASH pentagon. SWE: Shear wave elastography; SWD: Shear wave dispersion; ATI: Attenuation imaging; BMI: Body mass index; NASH: Non-alcoholic steatohepatitis.
