Indeterminate liver lesions in cancer
نویسنده
چکیده
It is important to distinguish liver metastases from incidental benign liver lesions which may be present in patients with cancer. In a minority of cases, sonography or CT may be sufficient to characterise benign lesions, but the range of sequences and contrast media available for liver MRI provides the opportunity for more specific diagnosis in the great majority of cases. Biopsy is rarely needed.
