A new diagnosis tool for the evaluation of liver fibrosis: Parametric Arrival Time imaging (PAT)

Introduction: Liver biopsy is the “gold standard” method for staging liver fibrosis, but it's an invasive procedure and is associated with risk of some complications. There are also noninvasive techniques for assessment of liver fibrosis such as elastography and biological tests, but these techniques can fail or generate false measurements depending on subjects conditions: food intake, ascites, obesity, etc. The aim of this study is to determine whether liver fibrosis can be evaluated using the parametric arrival time imaging (PAT) using contrast enhanced ultrasonography (CEUS). Material and method: Ultrasonogra…
