Cerebral embolism is the leading cause of ischemic stroke. Detection of microembolic signals [MES] in cerebral circulation is uniquely attained by several transcranial Doppler techniques, and can not be obtained with any other available imaging modality. Albeit no uniform picture has emerged from the studies, presence and amount of MES can identify a high-risk status in the setting of potential arterial or cardiac sources of cerebral embolism. Real-time MES monitoring during vascular procedures with high cerebral embolism risk seems also promising. The potential of MES detection in improvement of patient care is usually acknowledged, even though several aspects remain yet to be scientifically established. We herein review theory, technique and clinical potential of the neurosonological emboli detection, and try to add to understanding of the journal readership about the recent development on this subject.
