Patients with cerebral embolism need to undergo a cranial MRI to observe the location of the embolism, the area of brain tissue necrosis, and the age of the lesion, which is helpful in assessing the severity of the disease and prognosis. Additionally, it is necessary to examine the cervical vasculature with Doppler ultrasound to check for the presence of carotid artery plaques, especially soft plaques which are prone to detachment and can form emboli, blocking cerebral vessels and potentially causing recurrence or exacerbation of cerebral embolism. Furthermore, an echocardiogram of the heart is required because another common source of emboli in cerebral embolism is mural thrombi in the heart, particularly in patients with arrhythmias or atrial fibrillation, who are more prone to form mural thrombi. Therefore, patients with cerebral embolism need to have an echocardiogram to check for the presence of mural thrombi. If present, anticoagulant medication is required for treatment. (Please use medications under the guidance of a professional physician.)
