[Computer-assisted ultrasonic B-scan texture analysis of experimental liver tumors].
Primary liver cancer has been induced experimentally in female Wistar rats by diaminoazobenzene intoxication or subcapsular liver implantation of Novikoff cell suspensions. The ultrasonic B-scan image of these malignant tumours are described via statistical texture parameters in respect of image brightness, microtexture and macrotexture. A discrimination of the tumour texture profiles is possible with an accuracy of about 80%. There are correlations between ultrasonic image parameters and histomorphological tissue components but there is no specific link between the histological tumour-type and these B-scan data.
