1. In a high-risk population, the pulsatility index of the middle cerebral artery is associated with severity of white matter change (WMC). Nonetheless, its ability to differentiate those with and without significant subclinical WMC is only fair.
2. Using transcranial Doppler ultrasonography as a stand-alone screening instrument is not recommended to detect subclinical WMC.
