Methods and materials
The study group consisted of cases that were found to have liver disease and sent to the department of Radiology for percutaneous liver biopsy by different clinics between December 2012 and June 2013.
Approval was taken from the hospital’s ethics committee for this prospective study.
Informed consent form was taken from all cases.
Sonoelastographic assessment was made before percutaneous liver biopsy.
Two different strain rates VPR and MPR were found via sonoelastography.
These rates were recorded to be compared with histopathology results.
Based on the histopathologic assessment,
the patients were grouped in four categories (F0: no fibrosis,
F1: mild fibrosis,
F2: moderate fibrosis,
F3: severe fibrosis).
ROC analysis was used for each strain rate to determine the best threshold values in all stages and diagnostic accuracy rates were found based on these threshold values.
Mann-Whitney U test was used for the comparison of the qualitative data and Kruskal-Wallis test was used for the comparison of the quantitative data.
Spearman’s Rank Correlation Test was used to assess the concordance between two strain rates.
