Micro-CT was performed to a thrombus specimen. This sample was fixed in formalin and preserved in ethanol. Specimen was stained with 0.3% PTA dissolved in 70% ethanol. Scan was performed with a Skyscan 1172 at a voltage of 50kV and 198μΑ without filter for a full rotation of 360o . This specimen was scanned at the highest camera resolution with an exposure time of 325ms. This scan was performed for the evaluation of the impact of aspirated thrombus burden on the post‐aspiration clinical and angiographical outcomes of patients with ST‐Elevated Myocardial Infarction (STEMI). Specimen was provided by Efstratios Karagiannidis (AUTH) and scanned by Eva Chatzinikolaou.
