摘要

Objective: To compare the diagnostic accuracy of ultrasound with that of magnetic resonance imaging (MRI) for injuries of the medial collateral ligament (MCL) of the knee. Materials and Methods: Fifty-one consecutive patients from September 1, 2014 to January 31, 2016 were included. Ultrasound of the knee MCL was performed by physiatrists, and the images were re-read by an experienced sonographer (also a physiatrist). MRI (magnetic resonance imaging) scans of the knee MCL were examined by radiologists and the reports were compared with the findings of the ultrasound. The knee MCL was determined to be injured or intact, and the correlation between MRI and ultrasound findings were calculated using the kappa ratio. Results: The kappa ratios between the MRI and re-read physiatrist reports, and that between the MRI and original ultrasound reports, were 0.41 and 0.24, respectively. Correlation between the original ultrasound reports and re-read reports was 0.4. Conclusion: In daily practice, the correlation between the findings of MRI and ultrasound for the diagnosis of knee MCL injury was poor-to-fair. Further studies are required to improve the diagnostic accuracy of ultrasound.

研究目的：探討利用超音波診斷膝蓋內側副韌帶損傷之正確性。研究方法：本研究中，總共蒐集了51位病人，其平均年齡為46歲。這51位病人的膝關節同時接受了磁振造影檢查及超音波檢查。其中超音波檢查由復健科醫師執行並判讀，而其檢查影像，會再由一位資深復健科醫師判讀。磁振造影檢查則由影像醫學部醫師判圖，將兩種檢查之判讀結果計算kappa ratio作為相關係數。結果：超音波與磁振造影在診斷膝關節內側副韌帶之相關性kappa ratio為0.24。若取較資深復健科醫師之判讀結果，則Kappa ratio略微提升至0.41。在兩位復健科醫師之間，kappa ratio則為0.4。結論：在現行臨床狀況下，超音波在診斷膝關節內側副韌帶損傷，與磁振造影之相關係數仍不盡理想，需更多努力以增加超音波在診斷膝蓋內側副韌帶之正確性。
