Figure 1

Cardiac Magnetic Resonance Imaging Scan of Patients From Both Study Groups, No Thrombus Aspiration (NTA) and Thrombus Aspiration (TA) at 48 Hours: show myocardial T2 and T2* maps along with late gadolinium enhancement (LGE) in short-axis views from representative patients in the NTA and TA groups. T2 and T2* maps of the myocardium have been overlaid on T2-weighted and T2*-weighted images. The red and blue arrows represent infarct segment (IS) and remote segment (RS) in the myocardium, respectively. Note that edema was greater (higher T2) in the NTA patient compared to the TA patient in the IS. Lower T2* within the infarct core (white arrow) in the NTA patient was indicative of myocardial hemorrhage and was associated with microvascular obstruction (MVO) observed on the LGE image (white arrow)
