Grading of Liver Cirrhosis Using Ultrasound

This study was aimed to classify and grade the liver cirrhosis in US images using ultrasonographic features in order to classify the liver grades into different classes according to the degree of fibrotic changes. An analytical case control study of abdominal ultrasound images of 53 adult subjects with liver cirrhosis. An ultrasound characteristics of different liver grade including (texture, echogenicity, and cirrhosis grade and ascites condition), was collected and analyzed using linear discriminant analysis used for the tissue classification. Also cross tabulation was done to assess the relationship between all these variables and liver grades. The study found that the cirrhosis texture reveal a different underlying pattern compared to the cyst and normal liver tissues with classification sensitivity for grade 0, 1, and 2 are 91.4 %, 63.6 % and 57.1 % respectively. The combination of the texture features throughout the different U/S image phases using linear discriminant analysis technique also was classified and the sensitivity and overall accuracy demonstrated here.
