[Comparative study of hepatic metastasis with different modality ultrasound scanners].

57 patients affected by liver metastases were examined with different types of dynamic ultrasound scanners (linear-sector-convex) in order to assess the advantages and the limits of each scanner and to evaluate if a better diagnostic accuracy is possible by using 2 types of scanner in the same patient. The results were estimated at 3 different levels: quantitative analysis where we considered only the presence or not of liver metastases; complex quantitative analysis where we also evaluate number and site of the metastases; qualitative structural analysis where we compared the ultrasonographic appearance of the metastases. All the results were evaluated by a personal computer with a special program and a statistical analysis was elaborated.
