Quantitative Analysis and Characterization of Liver Diseases using Ultrasound Scans

This is a retrospective study done to evaluate the role of ultrasound in classification of diffuse liver diseases mainly Hepatitis (B) and Cirrhosis with normal liver, in which there were 179 cases (60 were normal cases, 59 had Cirrhosis and 60 had Hepatitis (B))) were subjected to be examined by a trans abdominal U/S scanning using Honda Aloka and General Electric scanners with 3.5 MHz probe to collect data about liver echo texture, shape, caudate and right lobe sizes, portal vein caliber, spleen size, shape of left edge of liver and presence of ascites. Any patient had liver tumor or fatty liver was excluded from this study. The collected data were analyzed using linear discrimination to identify ultrasound finding for each disease. The results of the study using linear discriminant analysis and measurable quantities for the livers, reveals that the normal liver can be identified by an accuracy of (100 %) while the sensitivity of the diagnosing liver cirrhosis was 98.3 % and for hepatitis type B the sensitivity was 90 % where 10 % of the cases showed measures similar to the normal liver, this occurs specially in early stage of disease.
