- W2758420499 abstract "The aim of our study was to evaluate the learning curve of obtaining reliable liver stiffness measurements (LSM), using ElastPQ. LSM of a trainee were compared to LSM of an elastography expert (with an experience of more than 500 examinations). Our study group included 50 subjects (mean age- 52.7 years, 66.6% men, mean BMI=25.6 kg/m2). Both the trainee and the expert obtained LSM for each subject, using ElastPQ (EPIQ 7, Philips Healthcare, Bothell, WA, USA). Reliable LSM were defined as the median value of ten measurements acquired in a homogenous area avoiding large vessels and with an IQR/ median < 30%. The learning curve was evaluated using the Receiver Operating Curve analysis using the expert’s results as reference. The trainee’s performance in obtaining reliable LSM was good (AUC: 0.735, 95% CI (0.557-0.913), p= 0.01). The trainee started to have similar results with the elastography expert after the 30th subject. When looking at the IQRs, they became significantly lower after the 30th subject (6.5±9.2 kPa vs 2.6±2.1 kPa, p= 0.03). Obtaining reliable LSM using ElastPQ can be easily achieved after 30 LS examinations." @default.
