...cells pathologically, she said. However, when the lesions were surgically removed and the tissue was examined under the microscope, 11.8% of the patients had cancer, she said. The atypical cells may be an indicator that cancerous cells exist in tissue that wasn't removed in the core biopsy, said Dr. Giess. ...MRI is better than PET for detecting small metastatic lesions in the liver
