Objective This review has summarized in detail the advances in computed tomography (CT) and magnetic resonance imaging (MRI) imaging in evaluating the efficacy of targeted therapy for gastrointestinal stromal tumor (GIST).Methods To summarize the image-related guidelines, consensus, international conference reports, and relevant knowledge of clinical research on the evaluation of the efficacy of GIST targeted therapy in recent years.Results The CT and MRI manifestation after targeted treatment of GIST was closely related to pathological changes, including necrosis, cystic degeneration, and bleeding. CT was the preferred imaging method. Functional magnetic resonance imaging, such as diffusion weighted imaging (DWI), had made some progress. The main criteria for evaluating the efficacy of GIST targeted therapy were RECIST 1.1 and Choi criteria.Conclusion CT and MRI play an important role in evaluating the efficacy of targeted therapy for GIST.
