Molecular Imaging Assessment of Immunotherapy Treatment Response

Immunotherapy has evolved and has revolutionized clinical oncology in recent years, achieving unprecedented clinical responses and outcomes. Precision medicine has the specific goal to treat the disease while limiting the damages derived from treatments. For that reason, it is important for radiologists to understand treatment response to immunotherapy, as development and approval of immunotherapeutics is increasing steadily. This article aims to educate radiologists on the mechanisms, benefits, and pitfalls of assessing immunotherapy response with molecular imaging.
