Treatment Response Evaluation in Hepatic Tumors using CT and MRI: Road Map for Radiologist

Abstract

The number of available methods for hepatic tumor treatment is steadily increasing. Except traditional surgical resection and systemic chemotherapy there are a lot of effective and increasingly used local methods such as Radiofrequency ablation, cryodestruction, transarterial chemoembolization. Radiologist should be able to assess treatment response and evaluate prognosis. We present review of literature on various systems for hepatic tumor treatment response evaluation. WHO, RECIST 1.0, RECIST 1.1, mRECIST and Choi criteria are thoroughly explained in terms of benefits and drawbacks. Also, texture analysis and diffusion-weighted imaging are discussed.
