Imaging procedures, such as contrast-enhanced ultrasound (CEUS), MRI, CT scan, or 18F-FDG PET, can help to differentiate between bland and tumor thrombosis, and a score (A-VENA) which incorporates alpha-fetoprotein level and imaging characteristics of the tumor (venous expansion; thrombus enhancement; neovascularity; and adjacent position to HCC) was also proposed [10]. The gene discussed is AFP; the disease is neoplasm.
