Post-embolization, the majority of patients face significant metal artifacts from stents or coils during routine CT scans, which can compromise the visibility of the images. In this case, we conducted a spectral CT scan with metal artifact reduction technology postoperatively to clearly visualize the coils and accurately evaluate the treatment’s effectiveness.
