摘要

BACKGROUND: The pathogenesis and imaging findings in whiplash-associated injury (WAD) are poorly understood and remain debatable. PURPOSE: 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. MATERIAL AND METHODS: 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. RESULTS: 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. CONCLUSION: 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.
