| Sumario: | <h4>Background/aims</h4>In a recent study, attenuation imaging (ATI) with ultrasound was used as a new approach for detecting liver steatosis. However, although there are many studies on ATI and controlled attenuation parameter (CAP) that prove their practicability, there are few studies comparing these two methods. As such, this study compared CAP and ATI for the detection and evaluation of liver steatosis.<h4>Methods</h4>A prospective analysis of 28 chronic liver disease patients who underwent liver biopsy, FibroScan® imaging, and ATI with ultrasound was conducted. The presence and degree of steatosis, as measured with the FibroScan® device and ATI, were compared with the pathological results obtained using liver biopsy.<h4>Results</h4>The areas under the receiver operating characteristic curve (AUROC) of ATI and CAP for differentiating between normal and hepatic steatosis were 0.97 (95% confidence interval [CI] 0.83-1.00) and 0.96 (95% CI 0.81-0.99), respectively. ATI has a higher AUROC than CAP does in liver steatosis, at 0.99 (95% CI, 0.86-1.00) versus 0.91 (95% CI, 0.74-0.98) in grade ≥ 2 and 0.97 (95% CI, 0.82-1.00) versus 0.88 (95% CI, 0.70-0.97) in grade = 3, respectively.<h4>Conclusion</h4>The ATI and CAP results showed good consistency and accuracy for the steatosis grading when compared with the liver biopsy results. Moreover, ATI is even better than CAP in patients with moderate or severe steatosis. Therefore, ATI represents a non-invasive and novel diagnostic tool with which to support the diagnosis of liver steatosis in clinical practice. |
