  • Figure 1
    Cardiac MRI T1 "black blood"

    T1 weighted image shows the formation is hypointense to myocardium.

     
    Area of Interest: Cardiac; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Tissue characterisation;
     
     
  • Figure 2
    "Black blood" IR T2 short axis

    T2 weighted fat sat imaging shows the mass is inhomogeneously hypointense.

     
    Area of Interest: Cardiac; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Tissue characterisation;
     
     
  • Figure 3
    Dynamic SSFP sequence

    Steady-state free precession (SSFP) cine imaging demonstrates a formation attached to the posterior leaflet of the mitral valve; this lesion showed protrusion into left atrium and ventricle.

     
    Area of Interest: Cardiac; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Tissue characterisation;
     
     
  • Figure 4
    Cardiac perfusion MRI

    Gd-DTPA first pass 4-chamber perfusion MRI showing perfusion defect of the lesion.

     
    Area of Interest: Cardiac; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Tissue characterisation;
     
     
  • Figure 5
    IR GRE late enhancement

    IR GRE late enhancement showing a rim of peripheral late enhancement.

     
    Area of Interest: Cardiac; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Tissue characterisation;
     
     
  • Figure 6
    Unenhanced CT

    CT scan, performed without administration of contrast medium, shows the lesion is hyperdense and widely calcific.
