  • Figure 1
    T1-weighted

    Submucosal lesion showing intermediate signal intensity on axial T1-weighted image

     
    Area of Interest: Pelvis; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Tissue characterisation;
     
     
  • Figure 2
    T2-weighted
     

    Submucosal rectal lesion with low-signal intensity on axial T2-weighted imaging

     
    Area of Interest: Pelvis; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Tissue characterisation;

    Submucosal rectal lesion with low-signal intensity on coronal T2-weighted imaging

     
    Area of Interest: Pelvis; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Tissue characterisation;
     
     
  • Figure 3
    DWI

    Low signal intensity on DWI with high b value (b=1000)

     
    Area of Interest: Pelvis; Imaging Technique: MR-Diffusion/Perfusion; Procedure: Diagnostic procedure; Special Focus: Tissue characterisation;
     
     
  • Figure 4
    T1-weighted fat-saturated

    Located on the recto-uterine pouch, notice the focus of high intensity signal on T1-weighted fat-saturated image. The submucosal lesion mantains intermediate signal intensity

     
    Area of Interest: Pelvis; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Tissue characterisation;
     
     
  • Figure 5
    Gadolinium enhanced axial T1-weighted image
     

    Lesion shows no enhancement following gadolinium contrast injection

     
    Area of Interest: Pelvis; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Tissue characterisation;

    Axial contrast-enhanced subtraction MR image showing no enhancement

     
    Area of Interest: Pelvis; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Tissue characterisation;
