Benign and Suspicious Ovarian Masses—MR Imaging Criteria for Characterization: Pictorial Review
Figure 1
Endometrioma. Axial T2-weighted image (a) shows an ovarian cystic mass with intermediate signal intensity. Axial T1 fat suppression weighted image (b) confirms the haemorrhagic nature of the cyst (endometrioma). Note a mural nodule located posterior on the left side of the wall (b, arrow). 3D fat-saturated T1-weighted Spoiled Gradient Echo images before (c) and after intravenous contrast injection with subtraction of precontrast and postcontrast sequences (d) demonstrate the lack of enhancement of the mural nodule due to blood clot.
