Overview
Ultrasound is the initial method of choice for the evaluation of liver mass. The evaluation of liver mass will depend on several characteristics, such as: vascular pattern, margins, location, distribution, and attenuation. Further evaluation of liver mass, should include other diagnostic studies, such as: Triphasic CT scan with complementary tumoral markers,or MRI. Other imaging study useful for the malignancy evaluation of liver mass is PET scanning, which may be helpful for the detection of occult disease and malignancy assessment.
