BACKGROUND
The spiral computed tomographic (CT) arthrography of the knee represents an alternative for MRI in the diagnosis of intraarticular lesions of the knee.
METHODS
We compared, in our retrospective study relates to fifty knees presenting meniscal or anterior cruciate ligament or cartilage lesions, the data of spiral computed tomographic (CT) arthrography and arthroscopy taken as "Gold Standard". The purpose was to determine the reliability of the spiral CT arthrography in the diagnosis of intraarticular derangements of the knee.
RESULTS
We found that sensibility and specificity of spiral CT tomography were respectively 86% and 81% for the detection of meniscal tears. They were respectively 60% and 86% for the detection of the cartilage lesions. The sensibility and specificity were respectively 47% and 94% for the detection of anterior cruciate ligament lesion.
CONCLUSION
the spiral CT arthrography, with its submillimeter spatial resolution, was reliable in the diagnosis of the meniscal and cartilage lesions whereas its value in the diagnosis of the anterior cruciate ligament tears remains to be determined.
背景
膝关节螺旋计算机断层扫描（CT）关节造影是诊断膝关节关节内病变时磁共振成像（MRI）的一种替代方法。
方法
在我们一项涉及50例存在半月板、前交叉韧带或软骨损伤的膝关节的回顾性研究中，我们将螺旋计算机断层扫描（CT）关节造影的数据与被视为“金标准”的关节镜检查数据进行了比较。目的是确定螺旋CT关节造影在诊断膝关节关节内紊乱方面的可靠性。
结果
我们发现，螺旋CT断层扫描检测半月板撕裂的敏感性和特异性分别为86%和81%。检测软骨损伤时，敏感性和特异性分别为60%和86%。检测前交叉韧带损伤时，敏感性和特异性分别为47%和94%。
结论
螺旋CT关节造影具有亚毫米级的空间分辨率，在诊断半月板和软骨损伤方面是可靠的，而其在诊断前交叉韧带撕裂方面的价值仍有待确定。
