Patient
male, 50 year(s)
 
 
  • Figure 1
    Asymmetric septal hypertrophic cardiomyopathy

    Four chamber SSFP and short axis images show asymmetric septal wall hypertrophy with maximal thickness in the mid wall.

     
    Area of Interest: Cardiac; Imaging Technique: MR; Procedure: Computer Applications-General; Special Focus: Genetic defects;
     
     
  • Figure 2
    LVOT obstruction associated with SAM

    CINE MR images demonstrate anterior motion of the mitral leaflet (SAM) in the systolic phase (B). A turbulent low signal jet (A) in the obstructed left ventricular outflow tract (LVOT) can also be seen.

     
    Area of Interest: Cardiac; Imaging Technique: MR; Procedure: Computer Applications-General; Special Focus: Genetic defects;
     
     
  • Figure 3
    Variable degree of fibrosis in hypertrophic cardiomyopathy

    Images of late enhancement in short-axis, 2-chamber and 4-chamber long-axis. Presence of diffuse enhancement, including in the LV mid anterior and apical regions. No abnormal enhancement in septal LV myocardium is...

     
    Area of Interest: Cardiac; Imaging Technique: MR; Procedure: Contrast agent-intravenous; Special Focus: Genetic defects;
     
     
  • Figure 4
    The diagnostic performance of T1-mapping in detecting fibrosis

    T1-mapping area under the curve is equal to 1069 ms (superior to 950 ms) in the septal LV wall.
