Diagnostic performance of diffusion-weighted MRI in the diagnosis of ovarian torsion: comparison of torsed and nonaffected ovaries
Özet
Introduction: The aim of this study was to evaluate the role of diffusion-weighted magnetic resonance imaging (MRI) in the diagnosis of ovarian torsion. Methods: We retrospectively identified 84 patients with surgically confirmed ovarian torsion. Seventeen patients with unclear ultrasound findings underwent MRI examination with two different magnetic resonance (MR) systems. Results: In ovarian torsion, the mean apparent diffusion coefficient (ADC) value of the torsed ovary was significantly lower than that of the nonaffected ovary in both MR systems (n = 17; 0.898 +/- 0.539 vs. 1.615 +/- 0.469 x 10(-3) mm(2)/s; P<.001). Conclusions: ADC comparisons were useful for detecting ovarian torsion. (C) 2016 Elsevier Inc. All rights reserved.
