Abstract<\/h2>

Objective<\/h3>
This study aimed to evaluate the performances of quantitative ultrasound (QUS) for the detection and assessment of hepatic steatosis when implemented using an ultraportable ultrasound scanner.<\/div><\/section>

Methods<\/h3>
Seven established QUS parameters were investigated. Ultrasound signals were acquired using a new ultraportable ultrasound device, the Hepatoscope. The feasibility of QUS using the Hepatoscope was first assessed\u00a0in vitro<\/i>. Clinical reliability, accuracy and staging capabilities were evaluated in 60 patients referred to a hepatology consultation for known chronic liver disease and enrolled in a prospective clinical investigation using the controlled attenuation parameter (CAP) as ground truth.<\/div><\/section>

Results<\/h3>
QUS parameters showed moderate (intra-class correlation coefficient [ICC] >0.50) to excellent (ICC >0.90) reliability. Two parameters, namely Lizzi-Feleppa mid-band fit and attenuation, were both reliable (ICC = 0.89 and 0.86, respectively) and correlated with the CAP (squared Pearson correlation coefficient of R2<\/sup>\u00a0= 0.65 and R2<\/sup>\u00a0= 0.6, respectively). For steatosis detection (S0 vs. \u2265S1), the two parameters yielded an area under the receiving operating characteristic curve of 0.90 and 0.86, respectively (95% confidence interval: [0.81\u20130.99] and [0.76\u20130.96], respectively).<\/div><\/section>

Conclusion<\/h3>
QUS can be reliably and accurately implemented on ultraportable ultrasound scanners. The combination of ultraportability and quantitative assessment of liver fat is promising for large-scale screening and monitoring of hepatic steatosis.<\/div><\/section>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
