  • Figure 1
    Axial T2W MRI - thigh muscle atrophy

    Axial T2W MR image showing extensive bilateral and symmetric thigh muscle atrophy with fatty infiltration. There is a relatively sparing of the rectus femoris, adductors and gracilis muscles.

     
    Area of Interest: Musculoskeletal soft tissue; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Genetic defects;
     
     
  • Figure 2
    Axial T2W MRI - highlighting vastus lateralis atrophy

    Axial T2W MR image at a different level highlights the marked atrophy and fatty infiltration of the vastus lateralis muscles (arrows).

     
    Area of Interest: Musculoskeletal soft tissue; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Genetic defects;
     
     
  • Figure 3
    Coronal T1 MRI - sparing of the adductors muscles

    Coronal T1 MR image highlighting fatty sparing of the adductors muscles (arrows).

     
    Area of Interest: Musculoskeletal soft tissue; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Genetic defects;
     
     
  • Figure 4
    Axial STIR MRI - difuse fatty infiltration

    Axial STIR MR image depicting diffuse muscular low signal intensity due to fatty infiltration. There is no edema.

     
    Area of Interest: Musculoskeletal soft tissue; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Genetic defects;
     
     
  • Figure 5
    Axial contrast MRI - enhancement of the quadratus femoris muscles

    Axial post-gadolinium MR image showing slight contrast enhancement of the adductors muscles and intense enhancement of the quadratus femoris muscles (arrows).

     
    Area of Interest: Musculoskeletal soft tissue; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Genetic defects;
     
     
  • Figure 6
    Axial contrast MRI - difuse muscle contrast enhancement

    Axial post-gadolinium MR image at a lower level than figure 5 showing diffuse muscle contrast enhancement.
