Abstract
In our study 97 metastatic liver lesions (48 patients) were examined using high field (1,5T) magnetic resonance system. During this investigation quantitative and qualitative analysis of the diffusion-weighted images were performed. All the metastatic foci are well-determined on raw diffusion-weighted images with factor b=50 s/mm2. Diffusion-weighted imaging allows visualization of metastases undetectable on conventional magnetic resonance images. High sensitivity of diffusion-weighted images in detection of abdominal lymph nodes has a great value as in staging of primary tumor as in assessment of therapy. It was shown that diffusion weighted imaging improves diagnostics of such lesions and should be included in the standard MR-protocol of studying these patients.
