Several different elastography techniques -- including shear-wave, MR, and transient elastography -- are all effective methods for diagnosing advanced fibrosis in patients with nonalcoholic fatty liver disease, according to researchers from the University of Pittsburgh.
In this Monday morning scientific session, Dr. Alessandro Furlan will present results from a study that included 62 patients, all of whom had biopsy-proven nonalcoholic fatty liver disease (NAFLD). The patients underwent ultrasound shear-wave elastography (SWE), MR elastography (MRE), and transient elastography (TE) within one year of the biopsy. Furlan's group evaluated the performance of each type of imaging exam using area under the receiver operating characteristic (ROC) curve analysis.
The area under the ROC curve was 0.80 for ultrasound shear-wave elastography, 0.85 for MR elastography, and 0.77 for transient elastography -- which suggests that physicians have a variety of tools at their disposal for diagnosing fibrosis in patients with NAFLD, the group wrote.

"2D SWE, MRE, and TE showed high accuracy for the diagnosis of advanced fibrosis in NAFLD with no significant difference at pairwise comparison," Furlan and colleagues concluded.
