Medical imaging is an important auxiliary means of disease diagnosis. In the process of diagnosis, diseases are usually presented in a static way, which is one of the characteristics of imaging diagnosis. However, this static representation of diseases imposes certain limitations, which can, to some extent, lead to the loss of medical humanities. Therefore, it is very important for imaging diagnostic doctors to correctly use philosophical thinking to understand, analyze, and solve problems. The reinforcement of philosophical thinking in imaging diagnosis entails commitment to the "patient-centered" perspective in medicine as well as the integration of comprehensiveness, regularity, and proactivity. This not only effectively trains the diagnostic thinking of imaging diagnostic doctors but also improves their humanistic quality, thereby addressing the problems associated with these limitations. This allows the diagnosis to be both technically accurate and emotionally attuned.
