Correlations between geometrical parameters measured on liver scintigrams and clinical observations.

Various geometrical data, resulting from anterior scans, of both normal and pathological livers were classified and analyzed statistically from two points of view: Firstly, a static study resulting from observations on pooled scans. This study showed that the frequency distributions of some geometrical parameters in the liver are essentially normal in character. It equally demonstrated that the dimensions of the parameters depend on the degree of the pathology of the liver. Secondly, a study which was carried out on repeated scans recorded on the same patient. It showed that the relative variations of some geometrical parameters of the liver are a function of its degree of pathology, whatever the types of abnormalities considered. The definition of a variable is suggested, the knowledge of which can help to establish the diagnosis.
