The ideograph of emboli sources investigated by TCD micro-emboli monitoring. a If MES are only detected on one side of MCA (like the left side as presented), and at the depth of a (MCA level), but not at the depth of b (ACA level), it then indicates that the embolus are originated from the MCA segment between a and b (black arrow indicates the embolus resource). b If MES are detected both at MCA and ACA on ipsilateral side, then the embolus are most likely derived from ICA of the same side (black arrows). c If MES are detected on both sides, then the embolus can be originated from the heart (black arrow), or ascending aorta (black arrow head). d If MES are detected at PCA but not MCA, it indicates that the embolus are originated from the posterior circulation, like BA (black arrow head), or VA (black arrows)
