Benign and Suspicious Ovarian Masses—MR Imaging Criteria for Characterization: Pictorial Review
Figure 2
Torsion of right ovary. Coronal T2-weighted image (a) shows an enlarged right ovary with numerous small peripheral cysts representing displaced follicles (arrow). The right ovary displays a peripheral annular hyperintensity on fat suppressed T1-weighted image which is indicative of hemorrhagic infarction (b, arrow). 3D fat-saturated T1-weighted Spoiled Gradient Echo image demonstrate the lack of enhancement of ovarian parenchyma (c, white arrow). Note: normal left ovary with small normal follicle (c, void arrow).
