- Pericarotid Fat as a Marker of Cerebrovascular Risk
This review article summarizes the key concepts related to pericarotid fat and its pathophysiology, examining its applicability as noninvasive imaging of plaque vulnerability and cerebrovascular events.
- Absence of the Susceptibility Vessel Sign with Cancer-Associated Hypercoagulability-Related Stroke
Cancer-associated hypercoagulability-related stroke is presumably caused by fibrin-predominant thrombi and is associated with the absence of the susceptibility vessel sign (sensitivity of 90%/specificity of 78%/ likelihood ratio of 4.06). This is in contradistinction to cardioembolic erythrocyte-predominant thrombi, which demonstrate hypointense signal on T2-weighted gradient-recalled echo images (susceptibility vessel sign).
