Spectral CT was used to prospectively collect medical images and clinical data related to breast cancer, evaluate the effect of image quality in the diagnosis of breast cancer, and evaluate the application value in the accurate staging of breast cancer, so as to provide a more accurate clinical basis for diagnosis, promote the development of individualized treatment, and ultimately improve the prognosis of patients.
