Two- and three-dimensional representations of acute stroke lesions analyzed in this study.

<p>Acute stroke lesions are shown in red overlayed on diffusion-weighted images in the first column. Three-dimensional reconstructions are illustrated in the second column. The third column shows application of morphological shape measures for lesions caused by cardioembolism (A), atherothrombosis (B) and small-vessel disease (C).</p

Representative illustration of three-dimensional lesion reconstruction.

<p>Stroke caused by arterial dissection of the left internal carotid artery, representations of the acute lesion are shown in red as two-dimensional overlay on diffusion weighted images (A) and as three-dimensional reconstructions (B). Bounding box of the lesion is illustrated in C.</p

Group comparison of morphological lesion shape measures for patients with embolic strokes of either cardiac or non-cardiac origin.

<p>Cardioembolic stroke was defined in patients classified by ASCOD as cardioembolism (C1 and C2; n = 37), a non-cardioembolic origin (n = 54) defined for strokes caused by atherothrombosis (A1, A2), arterial dissection (D1) and other known causes (O1); Multiple arterial pattern is defended as lesions located in at least two of the main arterial territories of the brain (left or right internal carotid artery or posterior circulation territory).</p
