The Mechanism Causing High-signal Intensity on Diffusion-weighted Imaging in Adnexal Torsion: Two Case Reports

We report two cases with adnexal torsion to assess the mechanism of very strong signal intensity in ovarian lesions on DW imaging using MR imaging such as [Formula: see text]-weighted imaging. MR imaging findings of the cases suggest that the very strong signal intensity on DW imaging is contributed...

description We report two cases with adnexal torsion to assess the mechanism of very strong signal intensity in ovarian lesions on DW imaging using MR imaging such as [Formula: see text]-weighted imaging. MR imaging findings of the cases suggest that the very strong signal intensity on DW imaging is contributed to cytotoxic edema with or without vasogenic edema, as well as oxyhemoglobin or extracellular methemoglobin.
