During the past three decades, different radiological criteria have been developed and used in tumor response evaluation obtained by imaging modalities such as computed tomography (CT) and magnetic resonance imaging (MRI). Response Evaluation Criteria in Solid Tumors (RECIST 1.1) have become the standard for assessment of response in solid tumors. More recently, modified RECIST (mRECIST) and immune-related RECIST (iRECIST) have been introduced for the evaluation of the hepatocellular carcinoma treatment response and for tumor response to immunotherapy. These criteria represent the gold standard for the evaluation of tumor response, according to tumor histotype and to selected therapy. The knowledge of these standardized criteria is crucial to ensure an objective evaluation, reducing variability, and avoiding misinterpretations that can modify treatment strategy. The purpose of this review article is to describe the characteristics of these criteria by enhancing differences among them.
