[A frequency analysis and evaluation of the criteria for dynamic CT and a test of the CT diagnosis of space-occupying lesions of the liver].
In a retrospective study the findings of dynamic CT investigations in 185 patients with histologically confirmed hepatic masses were analysed and related to 47 criteria which have been described in the literature. The criteria with the highest value for making a specific diagnosis have been defined for seven different lesions (abscess, adenoma, FNH, haemangioma, adenocarcinoma metastases, metastases from other tumours, HCC). We found agreement with the literature in the following: the target phenomenon for abscesses, central scarring for FNH, spreading enhancement for haemangiomas and irregularity of the liver contour in the absence of subcapsular tumours for HCC. By combining a number of criteria it was possible to suggest the type of lesion retrospectively. The predictive value was found to range from 73% to 100%, a definite diagnosis was possible in only 64%.
