  • Figure 1
    MRI examination
     

    Transverse T1-weighted image shows an ovoid, well-delineated right adnexal mass lesion (arrow), mainly isointense to the normal uterus (long arrow).

     
    Area of Interest: Genital / Reproductive system female; Imaging Technique: MR; Procedure: Comparative studies; Special Focus: Neoplasia;

    Transverse T2-weighted image depicts inhomogeneous right adnexal mass (arrow), mainly isointense to normal myometrium (not shown on these images). Small hyperintense area (long arrow) within the lesion, corresponding...

  • Figure 2
    MRI-DCE examination
     

    Dynamic contrast-enhanced fat-suppressed T1-weighted image (early phase) reveals strong and heterogeneous lesion enhancement (arrow).

     
    Area of Interest: Genital / Reproductive system female; Imaging Technique: MR-Diffusion/Perfusion; Procedure: Comparative studies; Special Focus: Neoplasia;

    Time signal intensity curves of tumour and normal myometrium.

  • Figure 3
    DWI
     

    Transverse DWI image (b= 800 s/mm2) shows lesion hyperintensity (arrow).

     
    Area of Interest: Genital / Reproductive system female; Imaging Technique: MR-Diffusion/Perfusion; Procedure: Comparative studies; Special Focus: Neoplasia;

    Corresponding ADC map demonstrates the tumour (arrow) as hypointense. The mean ADC value within the mass is 0.76 ×10–3 mm2/s.
