摘　　要：目的探讨MRI基于受限回波间距的快速梯度回波类CT成像(FRACTURE)序列与CT图像评估膝关节和踝关节骨质改变的一致性。方法回顾性收集2020年11月至2021年11月大连医科大学附属第一医院行CT及MRI FRACTURE序列检查的膝关节或踝关节患者, 共17例, 其中膝关节14例, 踝关节3例。依据关节组成骨数量共纳入80个组成骨, 其中股骨及髌骨各14个, 胫骨及腓骨各17个, 距骨、足舟骨、内侧楔骨、中间楔骨、外侧楔骨及跟骨各3个。由2名观察者分别通过CT及FRACTURE图像对关节组成骨的骨折、骨质增生、骨质破坏进行评估。采用Kappa检验分析观察者间采用CT和FRACTURE图像对关节组成骨病变评估的一致性。结果观察者1通过CT和FRACTURE图像对骨折、骨质增生、骨质破坏一致性评估的Kappa值(95%CI)分别为0.925(0.823~1.027)、0.905(0.799~1.011)和0.895(0.752~1.038), 观察者2分别为0.963(0.892~1.034)、0.933(0.843~1.023)、0.886(0.731~1.041)。观察者1和观察者2通过CT图像对骨折、骨质增生、骨质破坏评估的一致性Kappa值(95%CI)分别为1.000(1.000~1.000)、0.937(0.851~1.023)、0.945(0.839~1.051), 通过FRACTURE图像分别为0.962(0.888~1.036)、0.966(0.899~1.033)、0.836(0.656~1.016)。结论对于评价膝关节、踝关节组成骨的骨折、骨质增生、骨质破坏, MRI FRACTURE序列与CT图像具有高度的一致性。Objective To explore the consistency of MRI fast field echo resembling a CT using restricted echo-spacing(FRACTURE)and CT in the evaluation of knee and ankle bone changes.Methods From November 2020 to November 2021,seventeen patients who underwent CT and MRI FRACTURE examinations of knee joint or ankle joint in the First Affiliated Hospital of Dalian Medical University were retrospectively collected,including 14 patients with knee joint examinations and 3 patients with ankle joint examinations.According to the number of joint components,80 components were included,including 14 for femur and patella,17 for tibia and fibula,and 3 for talus,scaphoid,medial cuneiform,medial cuneiform,lateral cuneiform and calcaneus,respectively.The fracture,hyperosteogeny,and bone destruction of the joint bones were evaluated by two observers using CT and FRACTURE images,respectively.Kappa test was used to analyze the consistency of CT and FRACTURE images between observers in the evaluation of joint bone lesions.Results The Kappa values(95%CI)of the consistency evaluation of fracture,hyperosteogeny,and bone destruction by CT and FRACTURE images were 0.925(0.823-1.027),0.905(0.799-1.011)and 0.895(0.752-1.038)respectively for observer 1,and were 0.963(0.892-1.034),0.933(0.843-1.023)and 0.886(0.731-1.041)respectively for observer 2.The Kappa values(95%CI)of the consistency evaluation of fracture,hyperosteogeny,and bone destruction by observers 1 and 2 via CT images were 1.000(1.000-1.000),0.937(0.851-1.023)and 0.945(0.839-1.051)respectively,and that by FRACTURE images were 0.962(0.888-1.036),0.966(0.899-1.033)and 0.836(0.656-1.016)respectively.Conclusion For the evaluation of fracture,hyperosteogeny,and bone destruction of knee joint and ankle joint,MRI FRACTURE sequence is highly consistent with CT.
