What does liver cancer look like on a ultrasound?

Increased densities: Liver cancer can look like single or multiple nodules of increased density on the ultrasound. However, ultrasound is not the best, nor is it the final test in the diagnosis of liver cancer. A ct scan with and without contrast or an MRI scan give better visualization. By ultrasound, it is sometimes difficult to differentiate a hemangioma (a benign lesion) from a liver cancer.
