  • Figure 1
    MR pseudoaneurysm - CINE sequences
     

    a) Three chambers view demonstrates the myocardium pseudoaneurysm (star), with a narrow neck (arrow), contained by pericardial tissue. Left ventricle; LA - Left atrium; SSFP - steady state free precession sequences.

     
    Area of Interest: Cardiac; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Aneurysms;

    b) Short axis view shows the typical location of pseudoaneurysm in the infero-lateral wall (star).

     
    Area of Interest: Cardiac; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Aneurysms;
     
     
  • Figure 2
    MR pseudoaneurysm - delayed enhancement
     

    Three chambers delayed enhancement phase shows the pseudoaneurysm (PA) contained by a fibrotic, enhanced pericardium (arrows).

     
    Area of Interest: Cardiac; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Aneurysms;

    Four chambers delayed enhancement phase shows the pseudoaneurysm (PA) contained by a fibrotic, enhanced pericardium (arrows).

     
    Area of Interest: Cardiac; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Aneurysms;

    Short axis delayed enhancement phase shows the pseudoaneurysm (PA) contained by a fibrotic, enhanced pericardium (arrows).

  • Figure 3
    MR pseudoaneurysm - thrombus

    Three chambers view delayed enhancement shows a non-enhanced mass within the pseudoaneurysm lumen, representing a large thrombus (T). PA - Pseudoaneurysm LV - Left ventricle; LA - Left atrium; A - Aorta.

     
    Area of Interest: Cardiac; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Aneurysms;
