Abstract<\/h2>\n
\n

Purpose<\/h3>\n
Hepatoscope\u00ae is an ultraportable ultrasound system with 50 Hz two-dimensional\u00a0transient elastography<\/a>\u00a0(2DTE) for liver stiffness measurement (LSM). It provides a quality index (QI) for individual stiffness values that is based on imaging features. This study evaluated the 2DTE intra- and inter-user repeatability in patients with\u00a0chronic liver diseases<\/a>\u00a0(CLD) for novice and expert operators across various QI conditions. We compared the performances with other imaging and non-imaging elastography techniques.<\/div>\n<\/div>\n
\n

Methods<\/h3>\n
This investigation was a prospective cross-sectional single-center study. One hundred CLD patients underwent LSMs with vibration-controlled transient elastography (VCTE\u2122), two-dimensional shear wave elastography (2DSWE) and 2DTE. Expert and novice operators each performed two consecutive exams with 2DTE, blinded to any output. Intra-class correlation coefficient for intra-, and inter-user repeatability were calculated as well as applicability for various QI conditions, and Spearman’s correlations against VCTE and 2DSWE were assessed.<\/div>\n<\/div>\n
\n

Results<\/h3>\n
Computing LSM as the median of 10 stiffness values with a QI>85 % yielded the best compromise between reliability and applicability. In this setting, expert and inter-operator repeatability showed significant improvement over the condition with no QI threshold (ICC = 0.81 and 0.79, respectively) and 95 % applicability. Novice repeatability was excellent with a more restrictive QI (ICC = 0.80). LSM with 2DTE demonstrated strong and moderate correlation with VCTE and 2DSWE (r<\/em>\u00a0= 0.63 and 0.55, respectively).<\/div>\n<\/div>\n
\n

Conclusion<\/h3>\n
Hepatoscope 2DTE provides a promising and reliable alternative for non-invasive liver stiffness assessment in patients with CLD. The application of the image-based QI enhances LSM reliability and consistency across novice and expert operators.<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
