【摘要】 目的 以關(guān)節鏡檢查結果為對照，比較三維穩態(tài)采集快速成像序列(3D FIESTA)和常規序列在診斷前交叉韌帶(ACL)損傷中的準確性。資料與方法 對50例患者的55個(gè)外傷膝關(guān)節行常規MRI(SET1WI，FSEPD/T2WI)和3D FIESTA序列掃描。依據MRI圖像表現將ACL損傷分級，分析比較上述序列對ACL損傷診斷的敏感性、特異性、準確性和Kappa值。

[Abstract] Objective Form the results of arthroscopy, the accuracy of three-dimensional fast imaging steady-state acquisition sequence (3D FIESTA) and conventional sequence (2D SE/FSE) in the diagnosis of the injury of anterior cruciate ligament is compared. Materials and Methods Do MRI (SET1WI, FSEPD/T2WI) and 3D FIESTA sequence scanning to 55 injured knees form 50 patients. Classifying the ACL injury based on MRI images, the sensitivity, specificity, accuracy and Kappa value of the above sequence to ACL injury in diagnostic are analyzed. Results The sensitivity, specificity, accuracy and Kappa values results of 3D FIESTA diagnosis of ACL injury are higher than those of conventional sequences (2D SE / FSE) ,the results are 94.6%, 77.8%, 89.1%, 0.745. Conclusion With short time of sequence image acquisition and high accuracy of ACL injury indicating, 3D FIESTA sequence is the supplementary of conventional sequence (2D SE / FSE) to knee examination.
前交叉韌帶(anterior cruciate ligament，ACL)是維持膝關(guān)節穩定性的重要結構，是膝關(guān)節中最易發(fā)生損傷的韌帶之一。隨著(zhù)關(guān)節韌帶病變外科治療手段的不斷改進(jìn)，臨床對檢測和準確判定韌帶病變程度和治療轉歸的要求更加迫切。MRI是一種公認的無(wú)創(chuàng )檢測膝關(guān)節損傷的影像學(xué)方法，能夠為ACL損傷提供診斷依據。近年來(lái)，一些針對ACL形態(tài)改變的特異MRI序列應用于臨床。其中，三維穩態(tài)采集快速成像序列(3D FIESTA)由于可以明顯縮短成像時(shí)間，近年來(lái)在實(shí)驗研究和臨床應用上受到廣泛的關(guān)注[1-3]。本研究以關(guān)節鏡為金標準，比較三維穩態(tài)采集快速成像(3DFIESTA)和常規序列(2DSE/FSE)診斷前交叉韌帶(ACL)損傷的準確性，為臨床應用提供更多依據。
