Thrombi, or clots, often occlude proximal segments of the cerebral arterial
circulation in acute ischemic stroke. Thromboembolic occlusion or thrombi
superimposed on atherosclerotic plaque are the principal focus of acute stroke
therapies such as thrombolysis or thrombectomy. We review the imaging
characteristics of thrombi on multimodal computed tomography and magnetic
resonance imaging, angiography, and ultrasonography, summarizing recent studies
that facilitate therapeutic decision-making from these noninvasive studies.
Information about the location, size, and imaging characteristics can be
ascertained using these techniques. Imaging findings in relation to occlusive
thrombus have been correlated with clot pathology, response to therapeutic
interventions, and clinical outcome. Diagnostic evaluation of occlusive thrombi
on noninvasive studies now constitutes an integral component of acute stroke
management.
