PURPOSE
To compare the efficacy of conventional magnetic resonance (MR) imaging, MR arthrography, and stress radiography in the detection of lateral collateral ligament abnormalities in patients with chronic ankle instability.
MATERIALS AND METHODS
Seventeen patients with chronic lateral ankle instability underwent stress radiography, MR imaging, and MR arthrography after intraarticular injection of gadopentetate dimeglumine. Imaging findings were correlated with surgical findings.
RESULTS
The anterior talofibular (ATF) ligament was torn in 14 patients, and the calcaneofibular (CF) ligament was torn in 10. MR arthrography was more accurate and sensitive in the detection of ATF tears than was MR imaging or stress radiography (P < or = .05). Associated injuries were detected with both MR imaging and MR arthrography.
CONCLUSION
MR arthrography is a sensitive technique for detecting and staging tears of the lateral collateral ligaments.
目的
比较传统磁共振（MR）成像、MR关节造影和应力位X线摄影在检测慢性踝关节不稳患者外侧副韧带异常方面的效能。
材料与方法
17例慢性外侧踝关节不稳患者在关节内注射钆喷酸葡胺后接受应力位X线摄影、MR成像和MR关节造影。影像学表现与手术所见相关。
结果
14例患者的距腓前（ATF）韧带撕裂，10例患者的跟腓（CF）韧带撕裂。在检测ATF韧带撕裂方面，MR关节造影比MR成像或应力位X线摄影更准确、更敏感（P≤0.05）。MR成像和MR关节造影均检测到了相关损伤。
结论
MR关节造影是检测外侧副韧带撕裂及分期的敏感技术。
