Objective To explore the clinical value of CT combined with MRI in the diagnosis of occult cerebrovascular malformation. Methods From January 2019 to December 2021, 30 patients with occult cerebrovascular malformation admitted to our hospital were selected as the research object. On admission, CT and MRI examinations were performed. Then, the accuracy of single examination regimen and combined examination regimen was statistically analyzed with postoperative pathological diagnosis as a reference, and the imaging characteristics of the disease were analyzed. Results After pathological examination, all 30 patients were diagnosed as occult cerebrovascular malformation. The accuracy of combined examination was higher than that of single examination, and the accuracy of MRI examination was higher than that of CT examination, the difference was significant (P < 0.05). CT examination showed irregular spots, high confounding density lesions, and strip calcification in the adjacent cortex. In MRI examination, there are many phenomena such as complicated signal and shadow of small blood vessels around the lesion. Conclusion CT combined with MRI in the diagnosis of occult cerebrovascular malformation patients has higher diagnostic accuracy than single examination, and can reflect the patients cerebrovascular status through multiple aspects, which has higher promotion value.
