The pathogenesis and imaging findings in whiplash-associated injury (WAD) are poorly understood and remain debatable.
To assess the ligaments and membranes in the craniocervical junction with magnetic resonance imaging (MRI) in patients with WAD and to compare them with healthy control subjects.
Twenty-eight patients with WAD were selected at random from a total number of 180 examined with MRI using 2-mm proton density (PD)-weighted images in three orthogonal planes at 1.5T. The patients were compared with 27 healthy control subjects without neck trauma.
High signal intensity of the alar and transverse ligaments was quite common and was reported at an average of about 50% both among patients and control subjects. The incidence of abnormalities of the tectorial and posterior atlantooccipital membranes was low in both groups. No statistically significant difference between control subjects and patients with WAD was revealed for any of the structures assessed. Additional fat-suppressed images seemed to reduce the number of reported anomalies.
Due to lack of significant differences between patients with WAD and healthy control subjects, it is not recommended that MRI with the current technique and classification system be used in the routine workup of patients with WAD.
挥鞭样损伤（WAD）的发病机制和影像学表现尚不清楚，仍存在争议。
利用磁共振成像（MRI）评估WAD患者颅颈交界区的韧带和膜，并与健康对照者进行比较。
从180例接受MRI检查的患者中随机选取28例WAD患者，在1.5T磁场下使用2mm质子密度（PD）加权图像在三个正交平面进行检查。将这些患者与27例无颈部外伤的健康对照者进行比较。
翼状韧带和横韧带的高信号强度相当常见，患者和对照者中平均报告率约为50%。两组中覆膜和寰枕后膜异常的发生率均较低。在所评估的任何结构中，对照者与WAD患者之间均未发现统计学上的显著差异。额外的脂肪抑制图像似乎减少了报告的异常数量。
由于WAD患者与健康对照者之间缺乏显著差异，不建议在WAD患者的常规检查中使用当前技术和分类系统的MRI。
