[The picture of focal liver disease in ultrasound, computer tomography and angiography]. 
In a group of 25 patients examined by sonography, computer tomography and angiography with diagnoses confirmed during operation and by histology, the author compared the efficiency of the individual methods and a complex examination.  Computer tomography proved to be the most efficient method which enabled, in addition to precise localization, appreciation of size and relation of the pathological focus to adjacent structures, to determine their nature in some.  The complex examination in indicated cases significantly increased the diagnostic efficiency.
