Clinical, electrocardiographic, and angiographic data, and results of MRI in both groups.
Figure 1.
Typical MR Images of thrombus obtained at 9.4 T.
Proton density (showing the amount of water), T1 and T2 weighted images (highlighting differences in T1 and T2 relaxation times respectively) of 3 samples obtained after thrombectomy. A) Thrombus, clotted blood, B) sample composed mainly of lipids and C) sample of mixed composition.
Figure 2.
Histological analysis of thrombus.
Histological images of blood thrombus of short (A, B), long (C, D) evolution time, and fibrin, marked with an arrowhead, rich (E, F) samples.
Figure 3.
T2 values of coagulated blood.
A, graph showing T2 values for coagulated blood. The first columns correspond to all blood samples, the others to groups divided according to their evolution time. White bars ST Resolution, full bars Non ST resolution. *statistical difference p<0.05. B corresponds to the receiver operating characteristic (ROC) curve obtained as described in the methods section. Area under the curve is 0.70, p = 0.03.
