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±0.469×10(-3)mm(2)/s; P<.001).
CONCLUSIONS
ADC comparisons were useful for detecting ovarian torsion.
引言
本研究的目的是评估扩散加权磁共振成像（MRI）在卵巢扭转诊断中的作用。
方法
我们回顾性确定了84例经手术证实为卵巢扭转的患者。17例超声检查结果不明确的患者使用两种不同的磁共振（MR）系统进行了MRI检查。
结果
在卵巢扭转中，两个MR系统中扭转卵巢的平均表观扩散系数（ADC）值均显著低于未受影响的卵巢（n = 17；0.898±0.539与1.615±0.469×10(-3)mm(2)/s；P <.001）。
结论
ADC比较有助于检测卵巢扭转。
