Incidental findings of acute myocardial infarction detected during ECG-gated and nongated thoracic CTA: A report of four cases

Figures

• 

  Fig. 1. Case 1. (A and B) ECG gated thoracic CT, lumen and curved reconstruction show abrupt interruption of opacification in the right coronary artery (RCA) suggestive of total occlusion (red asterisk). (C) Cardiac CT, short axis view shows subendocardial hypodensity in the septal-inferior and inferior segments of the mid-apical myocardium, territory of RCA, suggestive of severe ischemia (white arrow).

• 

  Fig. 2. Case 2. (A and B) ECG gated thoracic CT, short axis and 4 chamber view show absent visualization of the lateral wall of the left ventricle with evidence of a pseudoaneurysmatic formation due to myocardial rupture contained locally by pericardial adhesions (white arrows).

• 

  Fig. 3. Case 2. ECG gated thoracic CT, lumen reconstruction shows abrupt interruption of opacification at the ostium of the circumflex coronary artery suggestive of total occlusion (blue arrows).

• 

  Fig. 4. Case 3 (A) Cardiac CT, 3D MPR reconstruction showing the evidence of apical thrombus (blue arrow); (B) Cardiac CT, axial plane with maximum intensity projection (MIP); subocclusive type opacification defect of the middle segment of the DA (red circle).

• 

  Fig. 5. Case 4 (A and B) Not ECG-gated toraco-abdominal CT, portal phase, short axis and 4 chambers plane showing evidence of septal-anterior and basal portion of myocardium hypodensity (blue arrows).
