METHOD OF DIFFERENTIAL DIAGNOSIS OF LIVER DISEASE

摘要

A method for differential diagnosis of liver diseases by conducting ultrasonic elastometry, characterized in that the pre-carried ultrasound character changes and update their localization Segment liver suspected Diffuse process conducted consistent elastometry four arbitrary zones various liver segments, when receiving the average data elastometry within from 6.5 to 12.5 kPa judge the presence of chronic diffuse process without cirrhosis; in obtaining average data elastometry ranging from 10.3 to 17.3 kPa judge the presence micronodular cirrhosis; suspected makronodulyarny or mixed cirrhosis elastometry performed alternately at the site with the greatest ehoplotnosti, the area with the smallest ehoplotnosti and on perifocal areas of these zones at a distance not more than 60 mm and not closer than 10 mm from the border areas of highest and lowest ehoplotnosti and when receiving elastometry data medium in the range of 15 to 35 kPa in zones highest and lowest density in the range of from 10 to 28 kPa in perifocal zone is judged that there makronodulyarnogo cirrhosis; with suspected metastatic nature hearth carried elastometry hearth center and two different location perifocal zones located at a distance of not more than 60 mm and not closer than 10 mm from the chamber boundary and in obtaining data elastometry in the range of 15 to 75 kPa in the outbreak and 3 4 to 5.9 kPa in perifocal areas judged on the presence of metastatic liver lesions.
