As incidence of HCC continues to increase, multi-modality imaging protocols have allowed us to understand their vital role in its detection, treatment and follow up. The unique vascular properties of primary liver cancer allows the treatment of these tumors with trans-arterial chemo- and radio-embolization (TACE/TARE), as well as percutaneous ablation. Accurate and reliable understanding of the angiographic appearance with concurrent interpretation of the follow up scans is paramount for the success of Loco-regional therapy. This educational exhibit aims to compare the angiographic findings of the lesions with the CT, 2D/3D ultrasound, and contrast ultrasound changes pre- and post treatment. This will help the reader to understand the relation between location, vascularity and the response of the tumor to treatment across modalities. Images are selected from 50 patients recruited in an IRB approved study who underwent (DEB)TACE/TARE or microwave/radiofrequency ablation between 2011-2014 to study role of multi-modality imaging in interventional management of focal liver tumors.
