Abstract

Interventional radiology has advanced significantly in recent decades, enhancing quality of life with treatments that are safer and less invasive. Despite these benefits, public awareness about vascular procedures remains limited, which affects the adoption of these therapeutic interventions by patients and physicians alike. Behavioral science theories, such as the theory of planned behavior (TPB) and the technology acceptance model (TAM), offer a robust framework to address this gap by shaping patient health-seeking behaviors. The TPB examines how attitudes, norms, and perceived control influence behavior, whereas the TAM focuses on technology acceptance based on ease of use and usefulness. Attitudes reflect opinions, subjective norms indicate social pressure, and perceived control relates to confidence in performing the behavior. Applying these models can improve patient acceptance and health care outcomes. Collectively, these models are instrumental frameworks in medical innovation, offering a systematic approach to evaluating and promoting the acceptance of new technologies. As health care continues to evolve, with rapid technological advancements, this narrative review underscores the potential role of these models in facilitating the successful integration of medical innovations, enhancing patient care, and optimizing health care practices.
